1.What portion or percentage of fatalities in construction are caused by falls?
1/3 of all accidents
2. What is Subpart M?
Subpart M deals with Machinery and equipment in the field.
Subpart M lays out the requirements and criteria for fall protection in construction workplaces. For example, it applies when workers are working at heights of 6 feet or mre above a lower level. It also covers protection from falling objects, falls from tripping over or falling through holes, and protection when walking and working around dangerous equipment without regard to height.
3. When must employers provide fall protection?
When the working area seems high and there might be a possibility of someone getting injured if he falls.
When the workers are working at a height of 6 ft. or higher.
4. Guardrail systems are barriers erected to prevent workers from falling to lower levels. Guardrail systems must be capable of withstanding a force at least __________ applied within 2 inches of the top edge, in any outward or downward direction, at any point along the top edge. 29 CFR 1926.502

5. A steep roof has a slope greater than 4 in 12 (vertical to horizontal). When working on a steep roof that has one or more unprotected side or edge 6 feet or more above lower levels, each worker must be protected by: Guardrail systems with toe boards, Safety net systems , or Personal fall arrest systems.
6. When safety nets are used, they must be installed as close as practicable under the walking or working surface on which workers are working and never more than ______ below that level. 29 CFR 1926.502(c)(1). When nets are used on bridges, the potential fall area from the walking or working surface to the net must be unobstructed. 29 CFR 1926.502(c)(1). All safety nets must be installed with sufficient clearance underneath to prevent a falling body from hitting the surface or structure below the net. 29 CFR 1926.502(c)(3).

10. Toeboards must be capable of withstanding, without failure, a force of at least 50 pounds applied in any downward or outward direction at any point along the toeboard. 29 CFR 1926.502(j)(2).

  • Toeboards must be at least 3.5 inches tall from their top edge to the level of the walking or working surface, must have no more than 0.25 inch clearance above the walking or working surface, and must be solid or have openings no larger than one inch in its greatest dimension. 29 CFR 1926.502(j)(3).
  • Where tools, equipment, or materials are piled higher than the top edge of a toeboard, paneling or screening must be erected from the walking or working surface or toeboard to the top of a guardrail system’s top rail or midrail, for a distance sufficient to protect workers below. 29 CFR 1926.502(j)(4).

11.CPSC (Consumer Product Safety Commission) warns that consumers can be electrocuted when they use ladders near overhead wires. Consumers may use ladders near overhead wires to clean gutters, paint structures, trim trees, and repair roofs and chimneys. Many over head power lines are not insulated.
12.CPSC (Consumer Product Safety Commission) advises to use a fiber glass ladder to avoid electrocutions. It also warns when workers or consumers move ladders if it touches electrical wire near the house:
They can get electrocuted
They cannot get electrocuted
13.When using a ladder which of the following are important?

  1. Be sure straight ladders are long enough so that the side rails extend above the top support point, by at least 36 inches.
  2. Don’t set up ladders in areas such as doorways or walkways where others may run into them, unless they are protected by barriers. Keep the area around the top and base of the ladder clear. Don’t run hoses, extension cords, or ropes on a ladder and create an obstruction.
  3. Don’t try to increase the height of a ladder by standing it on boxes, barrels or other materials. Don’t try to splice two ladders together.
  4. Do not apply personal or job stickers/decals.
  5. Set the ladder on solid footing against a solid support. Don’t try to use a stepladder as a straight ladder.
  6. Place the base of straight ladders out away from the wall or edge of the upper level about 1 foot for every 4 feet of vertical height. Don’t use ladders as a platform, runway or scaffold.
  7. Tie in, block or otherwise secure the top of straight ladders to prevent them from shifting.
  8. To avoid slipping on a ladder, check your shoes for oil, grease or mud and wipe it off before climbing.
  9. Always face the ladder and hold on with both hands when climbing up or down. Don’t try to carry tools or materials with you.
  10. Don’t lean out to the side when you’re on a ladder. If something is out of reach, get down and move the ladder over.
  11. Most ladders are designed to hold only one person at a time. Use by two workers may cause the ladder to fail or throw the ladder off balance.

14.Which of the following are important when designing scaffolding?

  2. Ties, guys, and braces for a scaffold must be installed according to the scaffold manufacturer’s recommendations. If the specifications are unknown then the standards at 29 CFR 1926.451(c)(1) must be followed.
  3. Barrels, boxes, kegs, horses, ladders, loose tile blocks, loose piles of bricks, A-frames or other unstable objects shall not be used as work platforms or to support scaffolds. Never use work platforms mounted on top of other work platforms.

  5. Falling object protection must be provided in areas where persons are required to work or pass under a scaffold.
  6. Overhead protection is required if employees working on scaffolds are exposed to overhead hazards.
