Safety Standards, Regulations, and Compliance
This domain tests whether you can identify the controlling requirement, distinguish legal duties from consensus guidance, and produce evidence of compliance. Expect questions that describe a facility or product and ask which standard or regulation applies.
Hierarchy and applicability
Regulations create legal duties, such as OSHA 29 CFR 1910.119 for process safety management and 1910.147 for lockout/tagout. Contracts can make a standard mandatory, for example MIL-STD-882E for a defense program. Consensus standards, such as IEC 61508 for functional safety, ISO 12100 for machinery risk assessment, and ISO 13849 for safety-related control systems, become binding through contract, incorporation by reference, or corporate policy. A contract may pin a specific edition, so the latest edition is not automatically controlling.
Compliance practice
Perform an applicability analysis, build a compliance matrix with evidence, document tailoring and deviations, train affected staff, and audit records. Verification should be objective: test reports, inspection records, calibration certificates, and acceptance signatures. Where a consensus standard is used as guidance but not required, do not present it as a legal substitute for the applicable regulation.
Worked example
A facility stores a flammable liquid above the OSHA process safety management threshold. A candidate cites ISO 12100 as the governing requirement. The better answer is that OSHA 1910.119 applies and requires process hazard analysis, management of change, incident investigation, mechanical integrity, and related program elements. ISO 12100 addresses machinery risk assessment and does not replace the legal PSM rule. Local fire and building codes may add requirements. Reasoning: start with legal applicability, then use consensus standards as supporting methods.
Traps that cost marks
- Applying the latest standard edition when the contract pins an older one.
- Treating a consensus standard as voluntary when it is contractually invoked.
- Claiming compliance without records or verification evidence.
- Failing to document tailoring and deviations.
