STSC Personal Protective Equipment in Construction 2

Question 1

What is the employer's responsibility regarding PPE under OSHA 29 CFR 1926.28?

Accepted Answer

Employers must provide and ensure use of appropriate PPE at no cost to employees

Answer

OSHA 1926.28 and the PPE payment rule (29 CFR 1910.132(h)) require employers to provide PPE at no cost to employees, except for safety-toed footwear, prescription safety glasses, and logging boots (which employers may require workers to provide).

Question 2

A worker is using a half-face air-purifying respirator (APR) with organic vapor (OV) cartridges in an environment with unknown contaminant concentration. Why is this potentially unsafe?

Accepted Answer

APRs cannot be used when contaminant concentration is unknown or may exceed 10 times the PEL (IDLH or above)

Answer

Air-purifying respirators require a known, non-IDLH atmosphere to be safely used. When concentrations are unknown, air-purifying respirators may not provide adequate protection — supplied-air or SCBA is required for unknown or IDLH atmospheres.

Question 3

Under OSHA's respiratory protection standard (29 CFR 1910.134), what must be included in a written respiratory protection program?

Accepted Answer

Procedures for respirator selection, employee training, medical evaluation, fit testing, maintenance, and program evaluation

Answer

OSHA 1910.134(c) requires a written respiratory protection program containing: selection procedures, medical evaluation requirements, fit testing procedures, use requirements, maintenance and care, training, and program effectiveness evaluation.

Question 4

A construction worker needs eye protection for grinding operations. Which eye protection is the MINIMUM required?

Accepted Answer

Safety glasses with side shields meeting ANSI Z87.1

Answer

For grinding, OSHA 1926.102 requires eye protection against flying particles. Safety glasses with side shields meeting ANSI Z87.1 are the minimum requirement for grinding, though goggles may be preferable for fine particle operations.

Question 5

What is the correct action if a hard hat sustains a significant impact, even if no visible damage is evident?

Accepted Answer

Remove it from service and replace it — internal damage may compromise protection

Answer

Hard hat shells can absorb impact energy through internal structural damage invisible to the naked eye. Any hard hat that sustains a significant impact must be removed from service and replaced, regardless of external appearance.
