Proper clothing is as essential as the proper selection and use of tools.
Wear clothes and gloves that are appropriate for the work and weather conditions.
Loose clothing is dangerous around power tools.
Workers shall wear shoes with closed toes at all times when on a construction site. Any worker wearing inappropriate footwear shall not be permitted to remain at a construction site.
Hard hats are to be worn as required or directed by a supervisor, and are to be made available to workers on each job site at all times.
Protective glasses are available for use on site.
A power tool should not be used without proper instruction on its use, and on what can happen if the tool is not used properly.
The instruction should be done by a qualified person (i.e. site supervisor,)
The instruction should be given to all workers, even experienced do-it-yourselfers.
The volunteer should use the power tool in the presence of the site supervisor, and until the supervisor is satisfied that the volunteer knows how to use the power tool properly.
Never lower or carry a power tool by its cord.
Clean tools daily.
Power tools should be checked for defective switches, cords, plugs, and proper grounding.
Defective tools should not be used
Defective tools should either be reported to the supervisor or labeled and brought to the tool room for repair immediately. (Do not wait until the end of the day.)
Always select the correct type and size of tool for your work, and be sure it is sharp and properly adjusted.
Guard against using any tool if the handle is loose or in poor condition.
Dull tools are hazardous to use because excessive force must be used to make them cut.
Dirt or oil on a tool may cause it to slip and cause an injury.
When using tools, hold them correctly. Most edge tools should be held in both hands with the cutting action away from yourself. Avoid using your hand or fingers as a guide to start a cut, but if it is necessary, use extreme caution.
When cutting long panels, the blade may bind, and the saw will catch and kick back towards the operator.
Use small wood wedges or shim shingles to spread the saw cut as you go along.
Keep the blade guard working.
A spring-actuated blade guard can often become bent and won't slide quickly, or the spring can become stretched so the return is slow.
Repair any damage to the guard as soon as it happens, and never tie the guard back out of the way.
Inspect a ladder before you use it.
If the ladder is unsafe, don't use it.
Look for wear and tear, loose rungs, and defects.
Use a ladder that will reach the work.
An extension ladder should reach three feet above the work level.
Move your ladder with your work.
If, while you are working, both of your shoulders are extended outside the ladder, you are reaching too far.
When using an extension ladder, use the four to one rule: For every four feet of height, move the bottom of the ladder one foot away from the wall.
Place your ladder on solid footing.
If there is danger of the ladder moving while your work, tie it down.
If there is danger that the ladder will be hit, barricade it.
Never use an aluminum ladder in the vicinity of electrical lines, and never use a ladder outdoors during inclement weather or on windy days.
Carry tools and materials in proper carrying devices, and keep your hands free for climbing. When climbing, always face the ladder.
All scaffolds must be equipped with a toe board to eliminate the possibility that tools or debris will be kicked or pushed on people below.
A scaffold must be designed to support four times the weight of the workers and the materials resting on it.
Scaffolding components that are not designed to be compatible should not be mixed.
Never use damaged or defective equipment, and avoid rusted parts as their strength is unknown.
When erecting scaffolding, provide adequate sills for the scaffold posts, and use base plates.
Use adjusting screws, and not blocks, when on an uneven grade.
Make sure you plumb and level scaffolding, and do not force end braces when constructing the scaffolding.
Use only properly graded and inspected lumber for planking.
This refers the neatness and good order of the construction site.
Maintaining good housekeeping contributes to the efficiency of the worker and is important in preventing accidents.
Clean up all rubbish and scrap materials on a daily basis.
Do not permit blocks of wood, nails, bolts, empty cans, pipe, wire, or other materials to accumulate on the work site since they interfere with work and can constitute a hazard.
Tools and equipment which are not being used should be stored in chests, panels, or tool boxes. This protects the tools and the workers.
Special care must be taken when you come in contact with any of these substances, or any unfamiliar substance.
If you discover asbestos fiber being used as pipe, boiler, or heating duct insulation, contact your supervisor immediately. DO NOT ATTEMPT TO REMOVE THE ASBESTOS FIBER ON YOUR OWN.
