Q1/ 40
A construction worker is performing overhead drilling into concrete, generating silica dust and small falling debris. The worker wears a Type I hard hat, standard safety glasses (ANSI Z87.1), and an N95 filtering facepiece. Chips of concrete fall and strike the worker's face above the glasses. What PPE deficiency exists?
✅ Correct Answer: B
1926.102(a)(1): eye and face protection shall be provided when there is a hazard from flying particles. Standard safety glasses protect the eyes but not the face — a face shield over safety glasses is required for overhead debris. 1926.100(a): employees shall wear protective helmets in areas where there is possible danger of head injury from impact or falling objects. A chin strap is needed when working overhead to prevent the hard hat from falling off. The Type I hard hat (A) is actually acceptable — Type II is for lateral impact, not a specific overhead requirement.
Q2/ 40
A carpenter on a commercial construction site is using a pneumatic nail gun for sheathing work. The carpenter wears leather gloves and safety glasses. The nail gun misfires and a nail penetrates the carpenter's leather glove and thumb. What PPE should have prevented or mitigated this injury?
✅ Correct Answer: B
1926.95(a): protective equipment shall be provided, used, and maintained in a sanitary and reliable condition. 1926.28(a): the employer is responsible for requiring the wearing of appropriate PPE in all operations where there is an exposure to hazardous conditions. Standard leather work gloves are designed for abrasion and minor cut protection, not ballistic puncture from a pneumatic nail. Puncture-resistant gloves (rated to ANSI/ISEA 105 Level 3 or higher) exist specifically for this hazard.
Q3/ 40
A crew cutting concrete with a walk-behind saw is exposed to noise measured at 102 dBA (8-hour TWA). The foreman provides foam earplugs with an NRR of 29. Workers complain they still hear loud noise. What does OSHA 1926.52 require?
✅ Correct Answer: B
1926.52(d)(1): when employees are subjected to sound levels exceeding those listed in Table D-2 (90 dBA for 8 hours), feasible administrative or engineering controls shall be utilized. If controls fail to reduce levels within the PEL, PPE shall be provided AND used. The NRR of 29 is the LABORATORY rating — OSHA derates earplugs by 50% (NRR-7/2), giving approximately 11 dB real-world attenuation: 102 - 11 = 91 dBA, still above the 90 dBA PEL. Dual protection (earplugs + earmuffs) or engineering controls (enclosures) may be necessary.
Q4/ 40
A welder on a bridge project is performing shielded metal arc welding (stick welding) overhead. What combination of PPE is specifically required for this type of work?
✅ Correct Answer: B
1926.353(c)(1): proper eye protective equipment for welding shall be provided. 1926.102(b)(1): filter lens shade numbers vary by current and process — stick welding at typical amperage requires shade 10-14. Overhead welding creates falling sparks and slag; synthetic clothing (C) will melt and cause severe burns. Leather or FR cotton is required. 1926.55 and 1926.353 require respiratory protection if welding fumes (hexavalent chromium from stainless, zinc from galvanized, etc.) exceed PELs.
Q5/ 40
On a multi-story construction site, the employer provides all workers with standard Type I, Class C hard hats (conductive). The electrical contractor is doing hot work on 480V switchgear nearby. What is the hard hat issue?
✅ Correct Answer: B
1926.100(b): hard hats must meet ANSI Z89.1 standards. ANSI Z89.1 classifies hard hats: Class G (General, 2,200V), Class E (Electrical, 20,000V), Class C (Conductive — NO electrical protection). Class C hard hats are typically made of aluminum or have conductive coatings — wearing one near 480V equipment creates a path to ground through the worker's head. The electrical contractor and anyone working near energized equipment need Class E hard hats.

Q6/ 40
A worker is required to wear fall protection (PFAS) while working 40 feet up on a cell tower. The worker also needs to wear a body belt-style tool pouch weighing 25 lbs with tools. Can the worker use the PFAS'S dorsal D-ring to also attach the tool pouch?
✅ Correct Answer: B
1926.502(d)(2): personal fall arrest systems shall not be used to hoist materials. The PFAS dorsal D-ring is a life-safety component — it must be available exclusively for fall arrest forces. Attaching a tool pouch adds static load, could interfere with deployment of the shock-absorbing lanyard, and could compromise the harness stitching. 1926.502(d)(15): PFAS anchorages must support 5,000 lbs per employee — but this refers to fall arrest forces, not accessory loads. Tools must be independently tethered to body belts or structural points.
Q7/ 40
A construction site has a high-noise area where the sound level is measured at 95 dBA. The employer posts a sign reading 'Hearing Protection Required' at the entry. Workers enter, grab foam earplugs from a dispenser, and go to work. Is this compliant with OSHA 29 CFR 1926.52?
✅ Correct Answer: B
1926.52(b): when PPE is required, the employer must ensure it is properly worn and maintained. Simply making earplugs available is not enough — OSHA requires: training on insertion technique (roll, pull, hold), fit verification, and supervision to ensure compliance. Studies show approximately 50% of workers insert foam earplugs incorrectly, reducing attenuation to near zero. The employer must also implement a hearing conservation program per 1926.52(d)(1) when levels exceed 90 dBA TWA.
Q8/ 40
A laborer is using a jackhammer to break up a concrete sidewalk. The vibration magnitude is measured at 12 m/s². After 4 hours of continuous use, the worker reports numbness and tingling in both hands. What does OSHA expect the employer to do?
✅ Correct Answer: B
While OSHA does not have a specific standard for hand-arm vibration, Section 5(a)(1) (General Duty Clause) applies: the employer must furnish a workplace free from recognized hazards. HAVS is a well-documented occupational disease — the European Union and ACGIH have established exposure limits. Recognized controls include: anti-vibration (AV) gloves meeting ISO 10819, job rotation limiting exposure duration, properly maintained tools with dampened handles, warm dry work conditions, and medical monitoring for early symptoms. Numbness and tingling are early warning signs of permanent nerve and vascular damage.
Q9/ 40
During a hot summer day (heat index 105°F), workers are pouring concrete on an exposed slab with no shade. One worker shows signs of heat exhaustion: heavy sweating, dizziness, and nausea. The foreman tells him to sit in the truck with the AC on for 15 minutes, then get back to work. What does OSHA require?
✅ Correct Answer: B
OSHA's Heat Illness Prevention campaign and the proposed heat standard (NPRM) require: water (accessible, cool), rest (in shade or AC until symptoms resolve), and shade (at 80°F+). Under the General Duty Clause, heat illness is a recognized hazard. Heat exhaustion can progress to heat stroke (core temp ≥104°F) within minutes — 15 minutes rest is not always sufficient. The worker should be monitored, cooled, and not be forced to return if symptoms persist. Employers should have a written heat illness prevention plan with acclimatization protocols.
Q10/ 40
A worker is required to wear fall protection for roofing work but also needs prescription safety glasses. The employer provides standard non-prescription safety glasses and tells the worker to wear them over his regular glasses. The worker's regular glasses keep fogging up underneath. What is the employer's obligation?
✅ Correct Answer: B
1926.102(a)(2)(i): eye and face PPE shall be distinctly marked to facilitate identification of the manufacturer. 1926.102(a)(1): employees whose vision requires the use of corrective lenses shall be protected by goggles or spectacles of one of the following types: (a) spectacles whose protective lenses provide optical correction, (b) goggles that can be worn over corrective spectacles without disturbing the adjustment of the spectacles, or (c) goggles that incorporate corrective lenses mounted behind the protective lenses. If option (b) creates additional hazards (fogging causing fall risk), the employer must provide option (a) or (c).
