Q

What are the specification of an OSHA certified guardrail system

A

Top rails must be at least 4 inch thick to
prevent cuts and lacerations

must be between 38 and 45 inches from the working
surface;

If wire rope is used, it must be flagged at least
every six feet with highly visible materials

Midrails, screens or mesh must be installed
when there are no walls at least 21 inches high.

Screens and mesh must extend from the toprail to the working level.

There can be no openings more than 19 inches;

The toprail must withstand at least 200 lbs. of force; the midrail must
withstand 150 lbs. of force;

The system must be smooth enough to protect workers from cuts and getting their clothes snagged by the rail.

If guardrails are used around holes at points of access, like a ladderway, a gate must be used to prevent someone from

falling through the hole, or
be offset so that a person cannot walk directly into the hole.

be as close as practicable under the working surface but neve more than 30feet below

be inspected every week for damage

have a border rope with a minimum strength of 5000 lbs

extend outward a sufficient distance

absorb the force of a 400lb drop test

all items in net must be removed as soon as possible

Q

personal fall arrest systems

A

a way to protect workers from falls

required when exposed to fall hazards 6 feet or more

required for workers on a suspended scaffold more than 10 ft above the working surface

33
Q

what are the major components of a personal fall arrest system

A

anchor and anchorage connector

connecting device

full-body harness

34
Q

what is a position system

A

systems that allow worker to work vertically

they require a separate fall protection system if the worker works at least 6ft from the ground

35
Q

What are the 4 types of lanyards

A

Rope- Offers some elastic properties for all arrests

Web- ideal for restraint purposes where fall hazards are less than 2 feet

Cable positioning-designed for corrosive or excessive heat environments and must be used in conjunction with shock absorbing devices

shock absorbers-best for fall restraints the fall arresting force will be greatly reduced

36
Q

What OSHAS fall protection standards

A

Provide working conditions that are free of known dangers.
Keep floors in work areas in a clean and, so far as possible, a dry condition.
Select and provide required personal protective equipment at no cost to workers.
Train workers about job hazards in a language that they can understand.

37
Q

what is a connector

A

a device used to secure a worker to their equipment

38
Q

Why are retractable lanyards popular in fall hazard heavy enviroments

A

they limit free fall to 2ft

have 3600 tensile strength

no shock absorber needed

39
Q

Why are retractable lanyards not always the best solution

A

they are subject to a hazard caused the pendulum effect which, if close enough to the ground, can still cause injury to the worker

40
Q

were should the attachment location of the body harness be,

A

in the center of the back near the shoulder level or above your head

41
Q

PFAS stands for

A
