History of the NEC
Overview
The National Electrical Code (NEC), or NFPA 70, is a regionally adoptable standard for the safe installation of electrical wiring and equipment in the United States. It is part of the National Fire Code series published by the National Fire Protection Association (NFPA), a private trade association. Despite the use of the term "national", it is not a federal law. It is typically adopted by states and municipalities in an effort to standardize their enforcement of safe electrical practices.
Background
The NEC is developed by NFPA's Committee on the National Electrical Code, which consists of twenty code-making panels and a technical correlating committee. Work on the NEC is sponsored by the National Fire Protection Association. The NEC is approved as an American national standard by the American National Standards Institute (ANSI). It is formally identified as ANSI/NFPA 70.
Publication
First published in 1897, the NEC is updated and published every three years, with the 2020 edition being the most current. Most states adopt the most recent edition within a few of years of its publication. As with any "uniform" code, jurisdictions may regularly omit or modify some sections, or add their own requirements. However, no court has faulted anyone for using the latest version of the NEC, even when the local code was not updated.
Enforcement
In the United States, anyone, including the city issuing building permits, may face a civil liability lawsuit for negligently creating a situation that results in loss of life or property. Those who fail to adhere to well known best practices for safety have been held negligent and could face fines and/or imprisonment if convicted. This liability and the desire to protect residents has motivated cities to adopt and enforce building codes that specify standards and practices for electrical systems.
Question: When was the National Electrical Code first published?
A)1897B)1789C)1987D)9817

Code Breakdown
The NEC is broken down into chapters, articles, sections, and subsections, informational notes, informational annexes, and an index. The table of contents is a useful tool to navigate the content of the code.
Introduction - Article 90
ARTICLE 90 is the Introduction Article of the NEC. This ARTICLE covers things like what the purpose of the code is, how the code is arranged, and how the code is enforced.
Chapters
The code is divided into 9 chapters. They are as follows:
Chapter 1 - General
Chapter 2 - Wiring and Protection
Chapter 3 - Wiring Methods and Materials
Chapter 4 - Equipment for General Use
Chapter 5 - Special Occupancies
Chapter 6 - Special Equipment
Chapter 7 - Special Conditions
Chapter 8 - Communication Systems
Chapter 9 - Tables
Articles
Each chapter is broken down into ARTICLES. Chapter 1, for example, includes 2 articles:
Chapter 1 - ARTICLE 100 - Definitions
Chapter 1 - ARTICLE 110 - Requirements for Electrical Installations
Parts
Each article is broken down into parts. ARTICLE 100, for example, looks like this:
ARTICLE 100 - Definitions
Part I - General
Part II - Over 1000 Volts, Nominal
Sections and Sub-Sections
Each part of an ARTICLE is divided into sections and sub-sections. These sections are what electrical professionals refer to as "codes." They are the actual text that makeup the majority of the NEC.
Informational Notes
Informational notes are scattered throughout the code. These notes are explanatory material that refer to related sections in the NEC or to other standards outside the NEC. They are not part of the requirements of the code.
Informational Annexes
The information annexes are examples provided to help electrical professionals better understand the code. They are simply tools and are not part of the requirements of the code.
Index
The index is a helpful tool to help you quickly find information your looking for on a specific subject within the code.

ARTICLE 90 Introduction
90.1 Purpose.
(A) Practical Safeguarding.
(B) Adequacy.
(C) Relation to Other International Standards.
Code Reference
90.1 (A) Practical Safeguarding. The purpose of this Code is the practical safeguarding of persons and property from hazards arising from the use of electricity.This Code is not intended as a design specification or instruction manual for untrained persons.
Practical Safeguarding of Persons and Property
Why do we install the way we do? Why do we use certain wire for indoor applications and others for outdoor? Why do we use standard EMT fittings for some installations and rain tight for others?
We find the answers to these questions in this section of ARTICLE 90. We install the way we do to protect people and property from the hazards that arise from the use of electricity. This Code provides electrical professionals with a technical document that will ensure the safe installation of electrical systems. Simply put, this Code is a minimum safety standard.
Not a Design Specification
The NEC again is simply a minimum safety standard. It does not tell us what type of light fixtures we should use. It does not stipulate that we should use round can lights instead of square ones or Decora receptacles instead of standard. It does tell us that our fixtures or receptacles need to be listed as safe, but aside from that, all design details are left up to the discretion of the owner or engineer.
Not an Instruction Manual
Would you be allowed to perform heart surgery without going to medical school? Would you want to be sent into war without proper training? There's a reason why electrical apprentices spend 4-5 years in an apprenticeship program. It takes many years to develop the knowledge and experience needed to understand and apply this Code.
Although untrained persons, such as homeowners, are allowed to make repairs and upgrades to their properties, this Code is not meant to be an instruction manual for them. Any repairs or upgrades made by homeowners are required to be in accordance with this Code, but the NEC is not a simple "step by step guide" that can be easily understood. It is a technical document that should be used and interpreted by trained professionals.

ARTICLE 90 Introduction
90.1 Purpose.
(A) Practical Safeguarding.
(B) Adequacy.
(C) Relation to Other International Standards.
Code Reference
90.1 (B) Adequacy. This Code contains provisions that are considered necessary for safety. Compliance therewith and proper maintenance result in an installation that is essentially free from hazard but not necessarily efficient, convenient, or adequate for good service or future expansion of electrical use.
Easy and Convenient
Wouldn't it be nice if we didn't have to put wire in conduit? How convenient would it be if we didn't have to spend so much time measuring, bending, cutting, and strapping. How much money could be saved if we could just free air wire in walls and above ceilings? It would be much more efficient and convenient, but would it be safe?
The Code does not exist to make things easy or convenient for us. Take gas stations for example. The dangers of electrical fires at gas stations are much greater than the dangers in an office building. That's why we have to use rigid conduit and explosion proof fittings. It's not efficient or convenient to use these materials, but it is safe.
Future Expansion
The Code does not require electrical professionals to plan for future expansions. Many building owners and engineers design electrical systems with extra breakers and spare circuits, but this is not required by the Code.
Also, the Code does not require us to tell the future. An installation that was Code compliant 50 years ago is probably not in compliance with today's code, but that doesn't mean it wasn't up to code back then. Again, the Code's main concern is that every installation, at the time it is installed, is safe.

Informational Notes
Overview
In the last slide we saw an Informational Note. In other sections of the Code we will see Notes. Before we get too far, it's important we understand what these notes are and how they differ from each other.
What are Informational Notes
Informational Notes are just information. They are not "Code Requirements". They cannot be cited by an electrical professional in a disagreement with an inspector. They simply provide the reader with more information on the specific code section in question. Informational Notes are provided throughout the Code and should be used to our advantage. Below is the note from the last slide:
Informational Note: IEC 60364-1, Section 131, contains fundamental principles of protection for safety that encompass protection against electrical shock, protection against thermal effects, protection against overcurrent, protection against fault currents, and protection against overvoltage. All of these potential hazards are addressed by the requirements in this Code.
What are Notes
Notes, however, are part of the code requirements. These notes are typically at the bottom of a code section or table, and further clarify the specific code section. Below is an example of a Note:
Note: If no adjustment or correction factors are required, this table shall be permitted to be applied.
This note is found at the bottom of Table 310.12 Single-Phase Dwelling Services and Feeders. It explains to us that if there are no adjustment or correction factors required, Table 310.12 shall be permitted to be applied.
Don't get them Mixed Up
Although Informational Notes are not Code Requirements, Notes are part of Code requirements and are there to provide further clarification to Code requirements. We need to make sure we don't get the two confused.

Ladder Safety
Overview
Each year, there are more than 164,000 emergency room-treated injuries and 300 deaths in the U.S. that are caused by falls from ladders.
Protection
Workers who are six feet or more above lower levels are at risk for serious injury or death if they should fall. To protect these workers, employers must provide fall protection and the right equipment for the job, including the right kinds of ladders, scaffolds, and safety gear.
Use the right ladder or scaffold to get the job done safely. For roof work, if workers use personal fall arrest systems (PFAS), provide a harness for each worker who needs to tie off to the anchor. Make sure the PFAS fits, and regularly inspect it for safe use.
Following these guidelines will help to reduce the hazards associated with the use of ladders in the workplace:
Read and follow all labels/markings on the ladder.
Avoid electrical hazards! – Look for overhead power lines before handling a ladder. Avoid using a metal ladder near power lines or exposed energized electrical equipment.
Always inspect the ladder prior to using it. If the ladder is damaged, it must be removed from service and tagged until repaired or discarded.
Always maintain a 3-point (two hands and a foot, or two feet and a hand) contact on the ladder when climbing. Keep your body near the middle of the step and always face the ladder while climbing (see diagram).
Only use ladders and appropriate accessories (ladder levelers, jacks or hooks) for their designed purposes.
Ladders must be free of any slippery material on the rungs, steps or feet.
Do not use a self-supporting ladder (e.g., step ladder) as a single ladder or in a partially closed position.
Do not use the top step/rung of a ladder as a step/rung unless it was designed for that purpose.
Use a ladder only on a stable and level surface, unless it has been secured (top or bottom) to prevent displacement.
Do not place a ladder on boxes, barrels or other unstable bases to obtain additional height.
Do not move or shift a ladder while a person or equipment is on the ladder.
An extension or straight ladder used to access an elevated surface must extend at least 3 feet above the point of support (see diagram). Do not stand on the three top rungs of a straight, single or extension ladder.
The proper angle for setting up a ladder is to place its base a quarter of the working length of the ladder from the wall or other vertical surface (see diagram).
A ladder placed in any location where it can be displaced by other work activities must be secured to prevent displacement or a barricade must be erected to keep traffic away from the ladder.
Be sure that all locks on an extension ladder are properly engaged.
Do not exceed the maximum load rating of a ladder. Be aware of the ladder’s load rating and of the weight it is supporting, including the weight of any tools or equipment.
Question: An extension or straight ladder used to access an elevated surface must extend at least how many feet above the point of support?

Electrical Safety Checklist
Overview
Electrical hazards can cause burns, shocks and electrocution (death). As an electrician, it is very important that you follow all of the below guidelines to protect yourself and your fellow co-workers. Assume that all wires are energized at lethal voltages. Never assume that a wire is safe to touch even if you think the circuit is off.
Proper procedures
Always use the LIVE DEAD LIVE method before working on any circuit.
LIVE DEAD LIVE steps:
Check your electrical testing device on a known live circuit to ensure it's working properly.
Check the circuit you will be servicing with your electrical testing device.
Re-check your electrical testing device on a known live circuit to ensure it's working properly.
Wear all required PPE when working on the construction site.
Wear a face shield or goggles if cutting, drilling, or shooting overhead.
Never repair electrical cords or equipment unless you qualified and authorized.
If working in damp locations, inspect electric cords and equipment to ensure that they are in good condition and free of defects, and use a ground-fault circuit interrupter (GFCI).
Always use caution when working near electricity.
Question: What should be used with extension cords when working in damp locations?
A)A ground-fault circuit interrupterB)An insulation testerC)An electrical meterD)An arc-fault circuit interrupter

Personal Protective Equipment
Overview
Personal Protective Equipment is the first line of defense in the workplace. Wearing proper safety equipment will help to ensure you return home from the job site every day.
Eye and Face Protection
Safety glasses or face shields are worn any time work operations can cause foreign objects to get in the eye. For example, during welding, cutting, grinding, nailing (or when working with concrete and/or harmful chemicals or when exposed to flying particles). Wear when exposed to any electrical hazards, including working on energized electrical systems.
Eye and face protectors – select based on anticipated hazards.
Foot Protection
Construction workers should wear work shoes or boots with slip-resistant and puncture-resistant soles.
Safety-toed footwear is worn to prevent crushed toes when working around heavy equipment or falling objects.
Hand Protection
Gloves should fit snugly.
Workers should wear the right gloves for the job (examples: heavy-duty rubber gloves for concrete work; welding gloves for welding; insulated gloves and sleeves when exposed to electrical hazards).
Head Protection
Wear hard hats where there is a potential for objects falling from above, bumps to the head from fixed objects, or of accidental head contact with electrical hazards.
Hard hats – routinely inspect them for dents, cracks or deterioration; replace after a heavy blow or electrical shock; maintain in good condition.
Hearing Protection
Use earplugs/earmuffs in high noise work areas where chainsaws or heavy equipment are used; clean or replace earplugs regularly.

Fall Protection
Overview
Falls are among the most common causes of serious work related injuries and deaths. Employers must set up the work place to prevent employees from falling off of overhead platforms, elevated work stations or into holes in the floor and walls.
Prevention
Employers must set up the work place to prevent employees from falling off of overhead platforms, elevated work stations or into holes in the floor and walls.
OSHA requires that fall protection be provided at elevations of four feet in general industry workplaces, five feet in shipyards, six feet in the construction industry, and eight feet in long shoring operations. In addition, OSHA requires that fall protection be provided when working over dangerous equipment and machinery, regardless of the fall distance.
To prevent employees from being injured from falls, employers must:
Guard every floor hole into which a worker can accidentally walk (using a railing and toe-board or a floor hole cover).
Provide a guard rail and toe-board around every elevated open sided platform, floor or runway.
Regardless of height, if a worker can fall into or onto dangerous machines or equipment (such as a vat of acid or a conveyor belt) employers must provide guardrails and toe-boards to prevent workers from falling and getting injured.
Other means of fall protection that may be required on certain jobs include safety harness and line, safety nets, stair railings and hand rails.

Trenching and Excavations
Overview
Excavation and trenching are among the most hazardous construction operations. OSHA defines an excavation as any man-made cut, cavity, trench, or depression in the earth’s surface formed by earth removal.
Dangers of Trenching and Excavation
Cave-ins pose the greatest risk and are much more likely than other excavationrelated accidents to result in worker fatalities.
Other potential hazards include falls, falling loads, hazardous atmospheres, and incidents involving mobile equipment.
Trench collapses cause dozens of fatalities and hundreds of injuries each year.
Protect Yourself - Do not enter an unprotected trench!
Trenches 5 feet (1.5 meters) deep or greater require a protective system unless the excavation is made entirely in stable rock.
Trenches 20 feet (6.1 meters) deep or greater require that the protective system be de-signed by a registered professional engineer or be based on tabulated data prepared and/ or approved by a registered professional engineer.
Protective Systems
There are different types of protective systems.
Sloping involves cutting back the trench wall at an angle inclined away from the excavation.
Shoring requires installing aluminum hydraulic or other types of supports to prevent soil movement and caveins.
Shielding protects workers by using trench boxes or other types of supports to prevent soil cave-ins.
Designing a protective system can be complex because you must consider many factors: soil classification, depth of cut, water content of soil, changes due to weather or climate, surcharge loads (eg., spoil, other materials to be used in the trench) and other operations in the vicinity.
Competent Person
OSHA standards require that trenches be inspected daily and as conditions change by a competent person prior to worker entry to ensure elimination of excavation hazards.
A competent person is an individual who is capable of identifying existing and predictable hazards or working conditions that are hazardous, unsanitary, or dangerous to employees and who is authorized to take prompt corrective measures to eliminate or control these hazards and conditions.
Access and Egress
OSHA requires safe access and egress to all excavations, including ladders, steps, ramps, or other safe means of exit for employees working in trench excavations 4 feet (1.22 meters) or deeper.
These devices must be located within 25 feet (7.6 meters) of all workers.
General Trenching and Excavation Rules
Keep heavy equipment away from trench edges.
Keep surcharge loads at least 2 feet (0.6 meters) from trench edges.
Know where underground utilities are located.
Test for low oxygen, hazardous fumes and toxic gases.
Inspect trenches at the start of each shift.
Inspect trenches following a rainstorm.
Do not work under raised loads.

Power Tools
Overview
Appropriate personal protective equipment such as safety goggles and gloves must be worn to protect against hazards that may be encountered while using hand tools.
Protection
Workplace floors shall be kept as clean and dry as possible to prevent accidental slips with or around dangerous hand tools.
Power tools must be fitted with guards and safety switches; they are extremely hazardous when used improperly. The types of power tools are determined by their power source: electric, pneumatic, liquid fuel, hydraulic, and powder-actuated.
To prevent hazards associated with the use of power tools, workers should observe the following general precautions:
Never carry a tool by the cord or hose.
Never yank the cord or the hose to disconnect it from the receptacle.
Keep cords and hoses away from heat, oil, and sharp edges.
Disconnect tools when not using them, before servicing and cleaning them, and when changing accessories such as blades, bits, and cutters.
Keep all people not involved with the work at a safe distance from the work area.
Secure work with clamps or a vise, freeing both hands to operate the tool.
Avoid accidental starting. Do not hold fingers on the switch button while carrying a plugged-in tool.
Maintain tools with care; keep them sharp and clean for best performance.
Follow instructions in the user's manual for lubricating and changing accessories.
Be sure to keep good footing and maintain good balance when operating power tools.
Wear proper apparel for the task. Loose clothing, ties, or jewelry can become caught in moving parts.
Remove all damaged portable electric tools from use and tag them: "Do Not Use."

Electrical Safety
Electric Tools
Overview
Electrical shocks, which can lead to injuries such as heart failure and burns, are among the major hazards associated with electric-powered tools. Under certain conditions, even a small amount of electric current can result in fibrillation of the heart and death. An electric shock also can cause the user to fall off a ladder or other elevated work surface and be injured due to the fall.
Protection
To protect the user from shock and burns, electric tools must have a three-wire cord with a ground and be plugged into a grounded receptacle, be double insulated, or be powered by a low-voltage isolation transformer.
Three-wire cords contain two current-carrying conductors and a grounding conductor. Any time an adapter is used to accommodate a two-hole receptacle, the adapter wire must be attached to a known ground. The third prong must never be removed from the plug.
Double-insulated tools are available that provide protection against electrical shock without third-wire grounding. On double-insulated tools, an internal layer of protective insulation completely isolates the external housing of the tool.
The following general practices should be followed when using electric tools:
Operate electric tools within their design limitations.
Use gloves and appropriate safety footwear when using electric tools.
Store electric tools in a dry place when not in use.
Do not use electric tools in damp or wet locations unless they are approved for that purpose.
Keep work areas well lighted when operating electric tools.
Ensure that cords from electric tools do not present a tripping hazard.
In the construction industry, employees who use electric tools must be protected by ground-fault circuit interrupters or an assured equipment-grounding conductor program.

Powder Actuated Tools
Overview
Powder-actuated tools operate like a loaded gun and must be treated with extreme caution. In fact, they are so dangerous that they must be operated only by specially trained employees.
Protection
When using powder-actuated tools, an employee must wear suitable ear, eye, and face protection. The user must select a powder level -- high or low velocity -- that is appropriate for the powder-actuated tool and necessary to do the work without excessive force.
The muzzle end of the tool must have a protective shield or guard centered perpendicular to and concentric with the barrel to confine any fragments or particles that are projected when the tool is fired. A tool containing a high-velocity load must be designed not to fire unless it has this kind of safety device.
To prevent the tool from firing accidentally, two separate motions are required for firing.
The first motion is to bring the tool into the firing position.
The second motion is to pull the trigger.
The tool must not be able to operate until it is pressed against the work surface with a force of at least 5 pounds (2.2 kg) greater than the total weight of the tool.
Safety precautions that must be followed when using powder-actuated tools include the following:
Do not use a tool in an explosive or flammable atmosphere.
Inspect the tool before using it to determine that it is clean, that all moving parts operate freely, and that the barrel is free from obstructions and has the proper shield, guard, and attachments recommended by the manufacturer.
Do not load the tool unless it is to be used immediately.
Do not leave a loaded tool unattended, especially where it would be available to unauthorized persons.
Keep hands clear of the barrel end.
Never point the tool at anyone.
When using powder-actuated tools to apply fasteners, several additional procedures must be followed:
Do not fire fasteners into material that would allow the fasteners to pass through to the other side.
Do not drive fasteners into very hard or brittle material that might chip or splatter or make the fasteners ricochet.
Always use an alignment guide when shooting fasteners into existing holes.
When using a high-velocity tool, do not drive fasteners more than 3 inches (7.62 centimeters) from an unsupported edge or corner of material such as brick or concrete.
When using a high velocity tool, do not place fasteners in steel any closer than 1/2-inch (1.27 centimeters) from an unsupported corner edge unless a special guard, fixture, or jig is used.

Lockout/Tagout
NOTE: THE INFORMATION IN THIS SLIDE IS EXTREMELY IMPORTANT. THIS SLIDE IS IN NO WAY A COMPREHENSIVE GUIDE TO LOCKOUT/TAGOUT PROCEDURES AND ONLY SERVES AS A REMINDER TO ELECTRICAL PROFESSIONALS OF THE DANGERS OF WORKING ON LIVE ELECTRICAL EQUIPMENT. PLEASE REFER TO YOUR EMPLOYER AND/OR OSHA REGULATIONS FOR THEIR SPECIFIC PROCEDURES ON LOCKOUT/TAGOUT.
Overview
Employees can be seriously or fatally injured if machinery they service or maintain unexpectedly energizes, starts up, or releases stored energy. As an electrical professional, it is absolutely imperative that you follow your employers guidelines to ensure your safety and the safety of your co-workers.
Lockout/Tagout procedures:
Before beginning service or maintenance, the following steps must be accomplished in sequence and according to the specific provisions of the employer's energy-control procedure:
Prepare for shutdown;
Shut down the machine;
Disconnect or isolate the machine from the energy source(s);
Apply the lockout or tagout device(s) to the energy-isolating device(s);
Release, restrain, or otherwise render safe all potential hazardous stored or residual energy. If a possibility exists for re-accumulation of hazardous energy, regularly verify during the service and maintenance that such energy has not re-accumulated to hazardous levels; and
Verify the isolation and de-energization of the machine.
Employees who work on de-energized machinery may be seriously injured or killed if someone removes lockout/tagout devices and re-energizes machinery without their knowledge. Thus, it is extremely important that all employees respect lockout/tagout devices and that only the person(s) who applied these devices remove them.
Before removing lockout/tagout devices, the employees must take the following steps in accordance with the specific provisions of the employer's energy-control procedure:
Inspect machines or their components to assure that they are operationally intact and that nonessential items are removed from the area; and
Check to assure that everyone is positioned safely and away from machines.
After removing the lockout/tagout devices but before re-energizing the machine, the competent person/responsible party must assure that all employees who operate or work with the machine, as well as those in the area where service or maintenance is performed, know that the devices have been removed and that the machine is capable of being re-energized.
Question: Who is the only person who can remove a lockout/tagout device?
A)The responsible partyB)Anyone can remove a lockout/tagout deviceC)The competent personD)The person who installed the device originally

Ground-Fault Circuit Interrupter
Overview
GFCI's protect professionals in the workplace from unsafe situations caused by a damaged or wet flexible extension cord or tools.
Definition
A GFCI is a fast-acting circuit breaker that senses small imbalances in the circuit caused by current leakage to ground and, in a fraction of a second, shuts off the electricity. GFCIs can be used successfully to reduce electrical hazards on construction sites.
Safety precautions that must be followed when using GFCI's include the following:
Each cord set, attachment cap, plug and receptacle of cord sets, and any equipment connected by cord and plug, except cord sets and receptacles which are fixed and not exposed to damage, shall be visually inspected before each day's use for external defects.
All equipment grounding conductors shall be tested for continuity and shall be electrically continuous.
Each receptacle and attachment cap or plug shall be tested for correct attachment of the equipment grounding conductor. The equipment grounding conductor shall be connected to its proper terminal.
All required tests shall be performed:
Before first use.
Before equipment is returned to service following any repairs.
Before equipment is used after any incident which can be reasonably suspected to have caused damage (for example, when a cord set is run over).
At intervals not to exceed 3 months, except that cord sets and receptacles which are fixed and not exposed to damage shall be tested at intervals not exceeding 6 months.

Heavy Lifting
Overview
Lifting heavy items is one of the leading causes of injury in the workplace. In 2001, the Bureau of Labor Statistics reported that over 36 percent of injuries involving missed workdays were the result of shoulder and back injuries. Overexertion and cumulative trauma were the biggest factors in these injuries.
Potential Hazards for electrical professionals include:
Large spools of wire
Bundles of conduit
Transformers
Switch gear
Heavy tools and machinery
Heavy light fixtures
Gang boxes
Lifting loads heavier than about 50 pounds will increase the risk of injury.
Possible Solutions:
Use mechanical means such as forklifts or duct lifts to lift heavy spools, transformers, switch gear, service sections, conduit, and machinery.
Use pallet jacks and hand trucks to transport heavy items.
Avoid rolling spools. Once they are in motion, it is difficult to stop them.
Use suction devices to lift junction boxes and other materials with smooth, flat surfaces. These tools place a temporary handle that makes lifting easier.
Use ramps or lift gates to load machinery into trucks rather than lifting it.
Maintain neutral and straight spine alignment whenever possible.
Usually, bending at the knees, not the waist, helps maintain proper spine alignment.
Order supplies in smaller quantities and break down loads off-site.
When possible, request that vendors and suppliers break down loads prior to delivery.
Prefabricate items in a central area where mechanical lifts can be used. Only transport smaller, finished products to the site.
Limit weight you lift to no more than 50 pounds. When lifting loads heavier than 50 pounds, use two or more people to lift the load.
Question: What is the maximum weight you should lift alone before asking for help?
A)50 poundsB)15 poundsC)500 poundsD)5 pounds
