Safety and Regulatory Compliance
Core concepts
This domain covers workplace safety and the regulatory obligations around manufactured products. Candidates should understand hazard identification, hierarchy of controls, machine safeguarding, lockout/tagout, personal protective equipment, chemical safety (SDS), and product compliance documentation such as declarations of conformity and traceability records.
What to know cold
- Hierarchy of controls: elimination, substitution, engineering controls, administrative controls, PPE - in that order of preference.
- Machine safeguarding: guards and interlocks prevent access to hazards; they are engineering controls.
- Lockout/tagout: energy isolation before maintenance; verify zero energy state.
- Chemical safety: SDS communicates hazards; labeling and storage rules follow.
- Product compliance: standards, testing, declarations, and record retention support market access.
Traps in questions
A common trap is selecting PPE as the primary control when an engineering control is feasible - PPE is the last resort. Another is treating training alone as sufficient for a serious hazard. Questions may also conflate a voluntary standard with a legal requirement; know which obligations are mandatory in the relevant jurisdiction.
Rule of thumb
Apply the hierarchy of controls top-down: try to eliminate or engineer out the hazard before relying on procedures or PPE. If the only control is administrative or PPE, document why higher controls are not feasible.
Worked example
Operators reach into a press to clear jams. Training and gloves (administrative and PPE) are weak controls. A fixed guard with an interlock (engineering control) is preferred; if access is truly required, a two-hand control or light curtain reduces exposure before PPE is considered.
