OSHA 10 Construction flashcards

32 cards. Read the term and the definition here. The deck at the top of this page is optional.

OSHA general duty clause

Section 5(a)(1) of the OSH Act requires each employer to furnish a workplace free from recognized hazards that are causing or likely to cause death or serious physical harm.

Fatality reporting time limit

An employer must report a work-related fatality to OSHA within 8 hours of learning of it, by telephone or online to the nearest OSHA office.

Hospitalization reporting deadline

Work-related in-patient hospitalizations, amputations, and losses of an eye must be reported to OSHA within 24 hours of the employer learning of the event.

OSHA inspection priority order

OSHA ranks inspections as imminent danger first, then fatality or catastrophe, then valid employee complaints and referrals, then programmed high-hazard inspections, then follow-up and monitoring visits.

Retaliation complaint filing window

Under Section 11(c) of the OSH Act, an employee who believes they were retaliated against for exercising safety rights must file a complaint with OSHA within 30 days.

Injury log entry timeframe

Employers required to keep OSHA records must enter each recordable injury or illness on the OSHA 300 Log within 7 calendar days of learning of the case.

OSHA 300A posting period

The annual summary of work-related injuries and illnesses, OSHA Form 300A, must be posted in a visible location from February 1 through April 30 of the following year.

Who pays for PPE

Employers must provide, at no cost to employees, all personal protective equipment required by OSHA standards, with narrow exceptions such as non-specialty safety-toe footwear and prescription safety eyewear worn off the job.

Citation contest deadline

An employer who disagrees with an OSHA citation must file a written Notice of Contest with the OSHA area director within 15 working days of receiving the citation.

Fall protection trigger height

In construction, conventional fall protection such as guardrails, safety nets, or personal fall arrest is required when employees work 6 feet or more above a lower level.

Scaffold fall protection threshold

Employees working on scaffolds more than 10 feet above a lower level must be protected by guardrail systems or personal fall arrest systems under 29 CFR 1926.451.

Steel erection fall protection height

During steel erection, fall protection is required at 15 feet above a lower level, with specific exceptions for connectors and deckers under 29 CFR 1926.760.

Guardrail height requirement

Top rails of guardrail systems must be 42 inches plus or minus 3 inches above the walking surface, with midrails near 21 inches and toe boards at least 3.5 inches high.

Fall arrest anchor strength

Personal fall arrest anchors must support at least 5,000 pounds per employee attached, or be designed under a qualified person's supervision with a safety factor of at least two.

Maximum free fall distance

A personal fall arrest system must limit free fall to 6 feet or less and stop the fall within a deceleration distance of 3.5 feet, with a rescue plan ready.

Hole cover requirements

Holes 2 inches or more in their least dimension must be covered or guarded; covers must be secured, marked HOLE or COVER, and support twice the intended load.

Warning line distance from edge

A warning line system must be erected at least 15 feet from the roof edge, at a height between 34 and 39 inches, using line with at least 500 pounds tensile strength.

Struck-by hazard categories

Struck-by injuries are grouped as struck by a flying, falling, swinging, or rolling object; controls include toe boards, debris nets, barricades, hard hats, and staying clear of suspended loads.

Crane swing radius barricade

Accessible areas within the swing radius of a crane's rotating superstructure must be barricaded so employees cannot be struck or crushed by the rotating equipment.

Excavation protective system depth

Excavations 5 feet or deeper require a protective system such as sloping, benching, shoring, or shielding unless a competent person determines there is no cave-in hazard.

Trench ladder travel distance

In trenches 4 feet or deeper, a ladder, stairway, or ramp must be provided so that workers travel no more than 25 feet laterally to reach it.

Spoil pile setback distance

Excavated material and equipment must be kept at least 2 feet back from the edge of an excavation to reduce cave-in risk from added loads near the edge.

Crane power line clearance

Cranes and derricks must keep at least 20 feet from overhead power lines rated up to 350 kV unless the line is de-energized or an insulating barrier is used.

GFCI requirement on sites

Construction 120-volt, single-phase, 15- and 20-ampere receptacles must have ground-fault circuit interrupter protection or be covered by an assured equipment grounding conductor program.

HazCom safety data sheets

Employers must obtain or develop a safety data sheet for each hazardous chemical in the workplace and keep it readily accessible to employees on each work shift.

Extension ladder 4-to-1 rule

An extension ladder must be set with its base 1 foot out from the wall for every 4 feet of working length to the upper support point.

Ladder extension above landing

A ladder used for access must extend at least 3 feet above the upper landing surface, and its top must be secured before the ladder is used.

Scaffold load capacity

Scaffolds must be designed to support at least 4 times the maximum intended load without failure, with platforms fully planked and inspected by a competent person before each shift.

Silica permissible exposure limit

The respirable crystalline silica PEL in construction is 50 micrograms per cubic meter as an 8-hour time-weighted average, with an action level of 25 micrograms per cubic meter.

Silica Table 1 controls

OSHA's Table 1 lists specified wet-cutting, vacuum, or water-fed tools and work practices that comply with the silica standard without requiring separate exposure monitoring.

Confined space attendant duty

Under 29 CFR 1926 Subpart AA, an attendant remains outside the permit space, monitors entrants, keeps an accurate count, and summons rescue without entering the space.

Call 811 before digging

Excavators must determine the location of underground utility installations before opening an excavation; calling 811 arranges free marking of buried utility lines.
