1Under the OSHA Hazard Communication Standard (HCS 2012), which pictogram indicates a chemical that may cause or intensify fire?
A.Exclamation mark symbol
B.Flame symbol
C.Gas cylinder symbol
D.Skull and crossbones symbol
Explanation: The flame pictogram identifies chemicals that are flammables, pyrophorics, self-heating, emit flammable gases when in contact with water, or are self-reactive and organic peroxides. This is one of nine standardized pictograms under the Globally Harmonized System (GHS) adopted by OSHA.
2What information must be included on a chemical container label under OSHA HazCom 2012?
A.Only the chemical name and manufacturer contact information
B.Product identifier, signal word, hazard statement(s), pictogram(s), precautionary statement(s), and supplier identification
C.Only the NFPA 704 diamond and expiration date
D.Only the chemical formula and physical state at room temperature
Explanation: OSHA requires six elements on chemical labels: product identifier, signal word (Danger or Warning), hazard statement(s), pictogram(s), precautionary statement(s), and supplier identification including name, address, and phone number. These elements align with GHS standards.
3Where on a Safety Data Sheet (SDS) would you find information about first aid measures for chemical exposure?
A.Section 2: Hazard Identification
B.Section 4: First-Aid Measures
C.Section 8: Exposure Controls/Personal Protection
D.Section 11: Toxicological Information
Explanation: Section 4 of the 16-section SDS format contains first-aid measures organized by route of exposure (inhalation, skin contact, eye contact, ingestion), plus most important symptoms/effects and indication of immediate medical attention needed.
4Which of the following is the MOST effective method for controlling workplace hazards according to the Hierarchy of Controls?
A.Substitution with less hazardous materials
B.Administrative controls
C.Elimination of the hazard
D.Personal protective equipment
Explanation: The Hierarchy of Controls, from most to least effective, is: Elimination (physically remove the hazard), Substitution (replace with less hazardous alternative), Engineering controls (isolate workers from hazards), Administrative controls (change work practices), and PPE (protect the worker). Elimination is the most effective because it removes the hazard entirely.
5A construction project requires work at heights. Which control measure represents an engineering control?
A.Requiring workers to attend fall protection training
B.Providing personal fall arrest systems for all workers
C.Installing guardrails around the work platform perimeter
D.Scheduling work during daylight hours only
Explanation: Installing guardrails is an engineering control because it physically isolates workers from the fall hazard. Training is administrative, fall arrest systems are PPE, and scheduling is administrative. Engineering controls are preferred over PPE and administrative controls per the hierarchy.
6According to OSHA 1926.501, at what height is fall protection required in construction work?
A.4 feet
B.6 feet
C.10 feet
D.15 feet
Explanation: OSHA 1926.501(b)(1) requires fall protection for construction workers at heights of 6 feet or more above lower levels. However, note that scaffolds require protection at 10 feet, and general industry (1910) requires 4 feet. The 6-foot rule is specific to construction.
7What is the maximum allowable free fall distance for a personal fall arrest system under OSHA 1926.502?
A.3 feet
B.6 feet
C.12 feet
D.15 feet
Explanation: OSHA 1926.502(d)(16)(iii) limits free fall distance to 6 feet or less. Additionally, the fall arrest system must be rigged such that an employee can neither free fall more than 6 feet nor contact any lower level. Shock-absorbing lanyards help limit arresting forces.
8A worker is using a positioning device on a vertical wall. What is the maximum allowable free fall distance for a positioning device?
A.2 feet
B.4 feet
C.6 feet
D.No free fall is permitted
Explanation: Positioning devices under OSHA 1926.502(e) must limit free fall to 2 feet or less. Positioning devices differ from personal fall arrest systems; they hold the worker in place while working, not for fall arrest, and must be rigged so the worker cannot fall more than 2 feet.
9What is the minimum approach distance for unqualified persons from overhead power lines carrying 50 kV or less?
A.6 feet
B.10 feet
C.15 feet
D.20 feet
Explanation: For work near overhead power lines, unqualified persons must keep at least 10 feet of clearance from lines rated 50 kV or less. For voltages over 50 kV, the minimum approach distance increases by 4 inches for each 10 kV (about 0.4 inch per kV) over 50 kV. Equipment such as cranes follows the Table A clearances in OSHA 1926.1408.
10Which OSHA construction standard (Subpart K) addresses lockout and tagging of circuits to control hazardous electrical energy?
A.1926.95 - Criteria for personal protective equipment
B.1926.417 - Lockout and tagging of circuits
C.1926.250 - General requirements for storage
D.1926.502 - Fall protection systems criteria
Explanation: OSHA 1926.417 (Subpart K, Electrical) requires that controls energizing lines and equipment be tagged, and that equipment or circuits be rendered inoperative with tags attached at all points where they could be energized. There is no 1926.147; the general industry control-of-hazardous-energy standard is 1910.147, which OSHA applies to construction machine servicing through the general duty clause and 1926.21.
