Ramsay Test Safety and OSHA Regulations 1 — Questions and Answers
Question 1: Under OSHA's Hazard Communication Standard (HazCom / GHS), what must be included on a chemical container label?
- Product identifier, signal word, hazard statements, pictograms, precautionary statements, and supplier information (Correct answer)
- Only the chemical name and hazard class
- The MSDS document affixed to the container
- Product name, company name, and emergency phone number only
Correct answer: Product identifier, signal word, hazard statements, pictograms, precautionary statements, and supplier information
OSHA's HazCom Standard (29 CFR 1910.1200) aligned with GHS requires 6 label elements: product identifier, signal word (Danger/Warning), hazard statements, GHS pictograms, precautionary statements, and manufacturer/supplier information.
Question 2: What is the maximum permissible noise exposure for an 8-hour workday per OSHA standards?
- 90 dBA for 8 hours (action level: 85 dBA for hearing conservation program) (Correct answer)
- 85 dBA for 8 hours
- 100 dBA for 8 hours
- 95 dBA for 8 hours
Correct answer: 90 dBA for 8 hours (action level: 85 dBA for hearing conservation program)
OSHA's noise standard (29 CFR 1910.95) sets the PEL at 90 dBA for 8 hours. The action level (requiring hearing conservation programs) is 85 dBA as an 8-hr TWA. Permissible exposure halves with every 5 dBA increase.
Question 3: What is the purpose of OSHA's Lockout/Tagout (LOTO) standard (29 CFR 1910.147)?
- To protect workers from unexpected energization or startup of machines during servicing by controlling hazardous energy (Correct answer)
- To prevent unauthorized access to electrical panels
- To require tagging of defective equipment awaiting repair
- To require lockable electrical disconnects on all motors
Correct answer: To protect workers from unexpected energization or startup of machines during servicing by controlling hazardous energy
LOTO (Control of Hazardous Energy) requires procedures to de-energize equipment and apply personal locks and tags before servicing. It covers all energy types: electrical, hydraulic, pneumatic, thermal, gravitational, and chemical.
Question 4: Under OSHA's Respiratory Protection standard, when is a fit test required?
- Before first use, when a different facepiece is used, and annually thereafter for tight-fitting respirators (Correct answer)
- Only when working with toxic materials
- Once at hire; no further testing required
- Every 5 years for all respirator types
Correct answer: Before first use, when a different facepiece is used, and annually thereafter for tight-fitting respirators
OSHA (29 CFR 1910.134) requires annual fit testing for tight-fitting respirators (half-face, full-face). Fit testing is also required before initial use and whenever there is a change in facepiece type or a physical change that could affect fit.
Question 5: What does OSHA's General Duty Clause (Section 5(a)(1) of the OSH Act) require of employers?
- To provide a workplace free from recognized hazards that are causing or likely to cause death or serious physical harm (Correct answer)
- To follow only OSHA standards that specifically apply to their industry
- To provide safety training in English only
- To report all accidents within 24 hours
Correct answer: To provide a workplace free from recognized hazards that are causing or likely to cause death or serious physical harm
The General Duty Clause is a catch-all requirement covering hazards not addressed by specific standards. Employers must address all recognized hazards, even if no specific OSHA standard exists for that hazard.
Question 6: What are the four classes of fires (A, B, C, D), and what does each involve?
- A = ordinary combustibles; B = flammable liquids/gases; C = electrical equipment; D = combustible metals (Correct answer)
- A = electrical; B = gas; C = chemical; D = dust
- A = all fires; B = building fires; C = chemical fires; D = deep-seated fires
- A = automobiles; B = buildings; C = chemicals; D = dust explosions
Correct answer: A = ordinary combustibles; B = flammable liquids/gases; C = electrical equipment; D = combustible metals
Class A: ordinary combustibles (wood, paper, cloth). Class B: flammable liquids and gases. Class C: energized electrical equipment (use Class C or CO2 extinguisher). Class D: combustible metals (magnesium, titanium — requires special dry powder). Class K is for cooking oils.
Question 7: What is the OSHA required minimum safe distance for working near overhead power lines (unqualified workers)?
- 10 feet for lines up to 50kV; greater distances for higher voltages (Correct answer)
- 5 feet for all voltage levels
- 3 feet for lines under 300V; 10 feet for higher voltages
- No minimum — PPE is sufficient protection
Correct answer: 10 feet for lines up to 50kV; greater distances for higher voltages
OSHA (29 CFR 1926.416 for construction; 1910.303 for general industry) requires unqualified workers to stay at least 10 feet away from power lines up to 50kV. Above 50kV, the minimum clearance increases by 4 inches per 10kV above 50kV.
Question 8: Under OSHA's Fall Protection standard (29 CFR 1926.502), at what height does fall protection become mandatory in construction?
- 6 feet above a lower level (Correct answer)
- 4 feet above a lower level
- 10 feet above a lower level
- Only when working over water or open excavations
Correct answer: 6 feet above a lower level
In construction (29 CFR 1926), OSHA requires fall protection at 6 feet above a lower level. In general industry (29 CFR 1910), the standard is 4 feet. Fall protection systems include guardrails, safety nets, and personal fall arrest systems (PFAS).
Question 9: What information must an OSHA 300 Log record?
- Work-related injuries and illnesses that result in days away from work, restricted work, job transfer, medical treatment beyond first aid, loss of consciousness, or diagnosis of a significant condition (Correct answer)
- All near-misses and first aid incidents
- Only fatalities and hospitalizations
- All accidents regardless of severity or work-relatedness
Correct answer: Work-related injuries and illnesses that result in days away from work, restricted work, job transfer, medical treatment beyond first aid, loss of consciousness, or diagnosis of a significant condition
The OSHA 300 Log (300/300A/301) records work-related injuries and illnesses meeting recordability criteria: death, days away from work, restricted duty, job transfer, medical treatment beyond first aid, loss of consciousness, or significant injury diagnosis.
Question 10: What is the purpose of a Safety Data Sheet (SDS), and which section contains first aid measures?
- Provides comprehensive hazard and safety information about chemicals; first aid measures are in Section 4 (Correct answer)
- Only provides environmental disposal information; first aid is in Section 1
- Provides purchasing information; first aid is in Section 16
- SDS covers only flammable chemicals; Section 7 covers first aid
Correct answer: Provides comprehensive hazard and safety information about chemicals; first aid measures are in Section 4
A 16-section GHS SDS provides comprehensive information: identification, hazards, composition, first aid (Section 4), firefighting, accidental release, handling/storage, exposure controls/PPE, physical/chemical properties, and more.
Question 11: What is the OSHA permissible exposure limit (PEL) concept, and how does it differ from ACGIH's TLV?
- PELs are legally enforceable OSHA limits; TLVs are recommended guidelines from ACGIH that are scientifically updated more frequently (Correct answer)
- PELs are recommended; TLVs are legally enforceable
- Both PELs and TLVs are equally enforceable
- TLVs are higher (less protective) than PELs for most substances
Correct answer: PELs are legally enforceable OSHA limits; TLVs are recommended guidelines from ACGIH that are scientifically updated more frequently
OSHA PELs are legal maximum exposure limits codified in regulations. ACGIH TLVs (Threshold Limit Values) are professional recommendations based on current scientific data, updated regularly. TLVs are generally more protective than outdated PELs.
Question 12: Under OSHA's Confined Space standard (29 CFR 1910.146), what makes a space a 'permit-required confined space'?
- The space is large enough to enter, has limited entry/exit, and has one or more serious hazards (atmospheric, engulfment, entrapment, or other recognized hazard) (Correct answer)
- Any space requiring a ladder to enter
- Any enclosed space in a building
- Any space requiring a key for entry
Correct answer: The space is large enough to enter, has limited entry/exit, and has one or more serious hazards (atmospheric, engulfment, entrapment, or other recognized hazard)
A permit-required confined space (PRCS) has all three characteristics of a confined space PLUS at least one of: hazardous atmosphere, engulfment material, internal configuration that could trap/asphyxiate, or other recognized serious safety hazard.
Question 13: What is the hierarchy of controls in OSHA's approach to hazard reduction, listed from most to least effective?
- Elimination → Substitution → Engineering Controls → Administrative Controls → PPE (Correct answer)
- PPE → Administrative → Engineering → Substitution → Elimination
- Engineering → Administrative → PPE → Substitution → Elimination
- Substitution → PPE → Administrative → Engineering → Elimination
Correct answer: Elimination → Substitution → Engineering Controls → Administrative Controls → PPE
The hierarchy of controls (most to least effective): 1. Elimination (remove the hazard), 2. Substitution (replace with less hazardous), 3. Engineering controls (isolate from hazard), 4. Administrative controls (change work procedures), 5. PPE (last resort).
Question 14: According to OSHA, within what timeframe must employers report fatalities and in-patient hospitalizations?
- Fatalities: 8 hours; in-patient hospitalizations/amputations/eye loss: 24 hours (Correct answer)
- All serious incidents: 24 hours
- Fatalities: immediately; all others: 72 hours
- Fatalities: 24 hours; all others: 72 hours
Correct answer: Fatalities: 8 hours; in-patient hospitalizations/amputations/eye loss: 24 hours
OSHA (29 CFR 1904.39) requires: fatalities reported within 8 hours; in-patient hospitalizations, amputations, or eye losses reported within 24 hours of learning of the incident. Reports can be made online, by phone, or at a local OSHA office.
Question 15: What does Arc Flash PPE category 2 (per NFPA 70E) require workers to wear?
- Arc-rated clothing with minimum 8 cal/cm² arc rating, arc-rated face shield or arc flash suit hood, arc-rated gloves, and other required PPE (Correct answer)
- Any leather gloves and a hard hat
- Standard cotton work clothes
- Only arc-rated gloves and safety glasses
Correct answer: Arc-rated clothing with minimum 8 cal/cm² arc rating, arc-rated face shield or arc flash suit hood, arc-rated gloves, and other required PPE
NFPA 70E PPE Category 2 (incident energy 1.2-8 cal/cm²) requires: arc-rated clothing ≥8 cal/cm², arc-rated face shield or arc flash suit hood, arc-rated gloves (Class 00+leather), hearing protection, safety glasses, and hardhat.
Question 16: What is an industrial hygienist's role in workplace safety?
- Anticipates, recognizes, evaluates, and controls chemical, physical, and biological hazards in the workplace to protect worker health (Correct answer)
- Performs medical surveillance and employee physicals
- Enforces OSHA citations on behalf of the government
- Designs fire suppression systems for industrial facilities
Correct answer: Anticipates, recognizes, evaluates, and controls chemical, physical, and biological hazards in the workplace to protect worker health
Industrial hygienists (IH) follow the AIHA/ABIH model: anticipate hazards before they occur, recognize them in the workplace, evaluate exposures (air monitoring, noise measurement), and recommend controls to protect worker health.
Question 17: What is 'ergonomics' in the context of industrial safety, and what does it address?
- Designing work tasks, tools, and environments to fit the human body and reduce musculoskeletal disorders (MSDs) (Correct answer)
- Physical fitness requirements for industrial workers
- The study of protective equipment sizing and fitting
- Training workers on proper emergency evacuation routes
Correct answer: Designing work tasks, tools, and environments to fit the human body and reduce musculoskeletal disorders (MSDs)
Ergonomics applies knowledge of human capabilities and limitations to design work that fits the worker. It addresses risk factors for MSDs: repetitive motion, awkward postures, forceful exertion, vibration, and contact stress.
Question 18: What is the OSHA standard for electrical safe work practices in general industry?
- OSHA 29 CFR 1910 Subpart S (Electrical) and NFPA 70E is the consensus standard it references for shock and arc flash protection (Correct answer)
- OSHA 29 CFR 1910.303 exclusively covers all electrical safety
- NEC (NFPA 70) is the only required electrical safety standard
- OSHA 29 CFR 1926 covers all electrical work in all industries
Correct answer: OSHA 29 CFR 1910 Subpart S (Electrical) and NFPA 70E is the consensus standard it references for shock and arc flash protection
OSHA 29 CFR 1910 Subpart S covers electrical safety in general industry workplaces. NFPA 70E (Standard for Electrical Safety in the Workplace) provides detailed safe work practice requirements that OSHA references and citations cite.
Question 19: Under OSHA's HazCom standard, what is the employer's responsibility regarding SDS access?
- Ensure employees have immediate access to SDS for all hazardous chemicals in their work area at all times during the work shift (Correct answer)
- Keep SDS binders in the safety office accessible only to supervisors
- Mail SDS to employees annually
- SDS access is only required for emergency response personnel
Correct answer: Ensure employees have immediate access to SDS for all hazardous chemicals in their work area at all times during the work shift
OSHA requires employers to maintain SDS for every hazardous chemical in the workplace and ensure employees can access them during their shift. Electronic SDS systems are acceptable if employees can access them immediately.
Question 20: What is the purpose of a Job Safety Analysis (JSA), also called a Job Hazard Analysis (JHA)?
- To identify and control hazards in each step of a job task before the work is performed (Correct answer)
- To assign blame for accidents after they occur
- To document employee training records
- To calculate workers compensation costs for specific jobs
Correct answer: To identify and control hazards in each step of a job task before the work is performed
A JSA/JHA breaks a job into sequential steps, identifies hazards at each step, and prescribes controls to eliminate or reduce those hazards. It is a proactive tool for preventing workplace injuries before they happen.
Question 21: What does OSHA require for employees working in areas with electrical hazards who are not qualified to work on energized equipment?
- They must maintain safe approach distances from energized equipment and are limited to tasks that do not require exposure to electrical hazards (Correct answer)
- They must wear all-rubber PPE whenever in the facility
- They may not enter any electrical room under any circumstances
- They must complete electrical training equivalent to a qualified person
Correct answer: They must maintain safe approach distances from energized equipment and are limited to tasks that do not require exposure to electrical hazards
OSHA distinguishes 'qualified' persons (trained in electrical safety and specific equipment) from 'unqualified' persons. Unqualified workers must stay outside the limited approach boundary and avoid exposure to electrical hazards.
Question 22: What is a 'near miss' in occupational safety, and why is it important to report?
- An unplanned event that did not result in injury but had the potential to; reporting identifies hazards before they cause injuries (Correct answer)
- An accident that resulted in minor injury only
- An incident that required only first aid treatment
- A condition noticed during a safety inspection
Correct answer: An unplanned event that did not result in injury but had the potential to; reporting identifies hazards before they cause injuries
Near misses (close calls) are unplanned events that didn't cause injury or damage but easily could have. Heinrich's Triangle shows that many near misses precede serious injuries. Reporting and analyzing near misses allows hazard correction before tragedy.
Question 23: What does the OSHA standard for personal protective equipment (PPE) require employers to provide?
- Conduct a hazard assessment, select appropriate PPE, provide PPE at no cost (except safety-toed footwear and prescription eyewear in some cases), and train employees on its use (Correct answer)
- Employees must purchase their own PPE; employers just specify the type
- PPE training is optional if the PPE is self-explanatory
- Employers provide PPE but are not required to train employees on it
Correct answer: Conduct a hazard assessment, select appropriate PPE, provide PPE at no cost (except safety-toed footwear and prescription eyewear in some cases), and train employees on its use
OSHA (29 CFR 1910.132) requires: workplace hazard assessment, PPE selection based on hazards, provide PPE at no cost to employees (OSHA requires employer-paid PPE for most types), and train employees on selection, use, and limitations.
Question 24: What is the minimum oxygen concentration in the atmosphere for entry into a confined space per OSHA?
- 19.5% to 23.5% oxygen is the acceptable range; below 19.5% is oxygen deficient, above 23.5% is oxygen enriched (Correct answer)
- Below 16% is the OSHA threshold for oxygen deficiency
- 15% to 21% is the acceptable range
- Only 21% (atmospheric normal) is acceptable
Correct answer: 19.5% to 23.5% oxygen is the acceptable range; below 19.5% is oxygen deficient, above 23.5% is oxygen enriched
OSHA defines an oxygen-deficient atmosphere as less than 19.5% O2, and oxygen-enriched as greater than 23.5% O2. Both are IDLH conditions. Continuous atmospheric testing is required during confined space entry operations.
Question 25: Under OSHA regulations, what is an employer required to do within 8 hours of a work-related fatality?
- Report the fatality to OSHA by calling 1-800-321-OSHA, online, or visiting a local OSHA office (Correct answer)
- File an incident report internally and submit to OSHA within 30 days
- Contact the insurance carrier only
- Post the incident on the OSHA 300 log and notify next of kin
Correct answer: Report the fatality to OSHA by calling 1-800-321-OSHA, online, or visiting a local OSHA office
Per OSHA 29 CFR 1904.39, work-related fatalities must be reported to OSHA within 8 hours. Reports can be made 24/7 via OSHA's toll-free number (1-800-321-OSHA), online at osha.gov, or at a local OSHA office.
Question 26: What is the 'hierarchy of controls' as it applies to machine guarding?
- Fixed barrier guards > Interlocked guards > Adjustable guards > Self-adjusting guards > Two-hand controls > Presence-sensing devices > PPE (Correct answer)
- PPE is the preferred method; guards are secondary
- Any guard type is equally acceptable if it prevents contact
- Guards are only required on equipment with exposed rotating parts
Correct answer: Fixed barrier guards > Interlocked guards > Adjustable guards > Self-adjusting guards > Two-hand controls > Presence-sensing devices > PPE
OSHA 29 CFR 1910.212 requires machine guarding to protect against point-of-operation hazards. Fixed barrier guards (most reliable) are preferred; interlocked guards, presence-sensing devices, two-hand controls, and restraints are alternatives when fixed guards are impractical.
Question 27: What is the purpose of OSHA's Process Safety Management (PSM) standard (29 CFR 1910.119)?
- To prevent or minimize the consequences of catastrophic releases of toxic, reactive, flammable, or explosive chemicals at facilities above threshold quantities (Correct answer)
- To regulate routine chemical handling in all industrial workplaces
- To require safety data sheets for all workplace chemicals
- To manage worker safety programs in all manufacturing facilities
Correct answer: To prevent or minimize the consequences of catastrophic releases of toxic, reactive, flammable, or explosive chemicals at facilities above threshold quantities
PSM applies to facilities with highly hazardous chemicals above threshold quantities. It requires 14 elements including process hazard analysis (PHA), operating procedures, mechanical integrity programs, management of change, and incident investigation.
Under OSHA's Hazard Communication Standard (HazCom / GHS), what must be included on a chemical container label?
