Heat stress and Hand-Arm vibration (NIOSH)
CSP written lesson, 9 min read. CSP Domain 6: Occupational Health and Applied Science
AI-drafted from the cited rules and fact-checked against them. Study aid, not site-specific safety advice. The official rule controls.
What you'll learn
- Distinguish the RAL from the REL and state who each applies to
- Describe NIOSH-recommended medical monitoring for heat-exposed workers
- Explain how acclimatization builds, fades and is regained
- Explain HAVS and why NIOSH sets no specific exposure limit
- Select administrative, work-practice and cold-protection controls for heat and vibration
What this lesson covers
This lesson covers how NIOSH frames occupational heat stress (the RAL versus the REL, medical monitoring, acclimatization) and hand-arm vibration syndrome, where NIOSH sets no exposure limit. These are the distinctions the exam tests, and the ones you rely on when choosing controls for hot work and vibrating tools.
