OSHA Outreach Training Program Requirements

OSHA #501 is for experienced general industry safety professionals who want to become authorized Outreach trainers teaching OSHA 10- and 30-hour General Industry classes. Prerequisites are OSHA #511 within the previous seven years plus five years of general industry safety experience (a CSP, CIH, or occupational safety degree substitutes for two years). The 4-day course (minimum 26 contact hours) covers 29 CFR 1910 standards with emphasis on the most hazardous and most-taught topics - hazard communication (1910.1200, now GHS Revision 7 aligned), lockout/tagout (1910.147), machine guarding (Subpart O), electrical (Subpart S), PPE and respiratory protection (Subpart I, 1910.134), and walking-working surfaces (Subpart D) - plus Outreach Training Program requirements (curriculum hours, 7.5-hour daily cap, 40-student limit, 30-day card requests, 5-year records) and adult learning techniques. Passing requires at least 40 of 50 points (80%) on the open-book written test, 50 of 75 points (67%) on a teaching presentation, and full attendance. Authorization runs four years, renewable through OSHA #503.

1Which provision of the Occupational Safety and Health Act requires employers to keep workplaces free from recognized hazards that are causing or likely to cause death or serious physical harm, even when no specific OSHA standard applies?
A.Section 5(a)(1), the General Duty Clause
B.Section 8(a), the inspection authority
C.Section 18, the state plan provision
D.Section 11(c), the anti-retaliation provision
Explanation: Section 5(a)(1) of the OSH Act, known as the General Duty Clause, obligates each employer to furnish employment free from recognized hazards causing or likely to cause death or serious physical harm. OSHA uses it to cite serious hazards not covered by a specific standard.
2Under 29 CFR 1904.39, an employer must report a work-related fatality to OSHA within what time frame?
A.24 hours
B.8 hours
C.72 hours
D.5 working days
Explanation: 29 CFR 1904.39 requires employers to report any work-related fatality to OSHA within 8 hours of learning about it, by phone to the area office, the 800-321-OSHA hotline, or the online reporting application.
3A maintenance worker suffers an amputation of a fingertip in a press at 9:00 a.m. on Tuesday and is treated at an outpatient clinic. Under 29 CFR 1904.39, when must the employer report this event to OSHA?
A.Within 8 hours, the same as a fatality
B.Only if the employee is later hospitalized overnight
C.Within 24 hours of learning about the amputation
D.No report is required because the injury was treated on an outpatient basis
Explanation: All work-related amputations, in-patient hospitalizations, and losses of an eye must be reported to OSHA within 24 hours of the employer learning of the event, regardless of where treatment occurred (29 CFR 1904.39(a)(2)).
4An establishment required to keep OSHA injury and illness records must post the Form 300A annual summary in the workplace during which period?
A.January 1 through March 1
B.All year, updated quarterly
C.February 1 through March 31
D.February 1 through April 30
Explanation: 29 CFR 1904.32 requires the Form 300A summary of the previous year's injuries and illnesses to be certified by a company executive and posted from February 1 to April 30 in a conspicuous location.
5After receiving an OSHA citation, an employer must post a copy of the citation at or near the location of the violation for how long?
A.3 working days or until the violation is abated, whichever is longer
B.15 working days in all cases
C.Until the informal conference is held
D.30 calendar days regardless of abatement
Explanation: Under 29 CFR 1903.16, the employer must post the citation at or near the place the violation occurred for 3 working days or until the violation is abated, whichever period is longer.
6An employer who wishes to contest an OSHA citation, penalty, or abatement date must file a Notice of Contest within what period after receiving the citation?
A.10 calendar days
B.15 working days
C.30 calendar days
D.60 calendar days
Explanation: The OSH Act gives employers 15 working days from receipt of the citation and proposed penalty to file a written Notice of Contest with the OSHA area director; otherwise the citation becomes a final order of the OSH Review Commission.
7Which situation receives the HIGHEST priority for an OSHA inspection?
A.A programmed inspection under a site-specific targeting plan
B.A formal written complaint from a current employee
C.An imminent danger situation where death or serious harm could occur immediately
D.A referral from a local building department
Explanation: OSHA's inspection priority order places imminent danger first, followed by fatalities and catastrophes, then complaints and referrals, and finally programmed (targeted) inspections.
8A worker cuts a forearm on sheet metal. The clinic closes the wound with two sutures and the worker returns to regular duty the same day. For OSHA 300 log purposes, this case is:
A.Not recordable because there were no days away from work
B.Not recordable because it was a single outpatient visit
C.Recordable only if the wound later becomes infected
D.Recordable because sutures are medical treatment beyond first aid
Explanation: Under 29 CFR 1904.7, a work-related injury is recordable if it results in medical treatment beyond first aid. Wound closure with sutures or staples is medical treatment by definition, so the case goes on the OSHA 300 log even with no lost time.
9An employee believes she was fired for filing an OSHA complaint. Under Section 11(c) of the OSH Act, she must file a whistleblower complaint with OSHA within how many days of the retaliatory action?
A.30 days
B.90 days
C.180 days
D.1 year
Explanation: Section 11(c) of the OSH Act protects employees from retaliation for exercising safety and health rights, but the complaint must be filed with OSHA within 30 days of the adverse action.
10Which statement about OSHA-approved state plans under Section 18 of the OSH Act is correct?
A.State plans may adopt standards less stringent than federal OSHA if approved
B.State plan standards must be at least as effective as federal OSHA standards, and state plans must cover state and local government workers
C.State plans cover only private-sector employers
D.Federal OSHA directly enforces all standards in state plan states
Explanation: Section 18 requires state plans to adopt and enforce standards at least as effective as federal OSHA's, and every state plan must cover state and local government employees - a group federal OSHA does not cover.
