Hazmat Awareness · Chapter 2 · Review · Awareness track

Regulations, Standards, and Laws

Referencing the content of hazardous materials awareness and operations at the awareness level

Federal and consensus standards set the training floor; local AHJs may add requirements but cannot ignore transport and worker protection rules.

Learning objectives (7)

Explain NFPA 470 role — NFPA 470 is the consolidated standard for hazardous materials and WMD response competencies.
Define hazmat employee — A person employed by a hazmat employer who affects hazmat transportation safety.
Describe shipping paper purpose — Documents required in transport listing proper shipping name, UN/NA ID, hazard class, and emergency contacts.
Contrast label vs placard — Labels mark individual packages; placards identify transport vehicles or large containers.
Summarize EPCRA community planning — Facilities report stored chemicals; local committees plan for releases.
List HAZWOPER training tiers — Awareness, operations, technician, specialist, and incident commander training levels with different hour requirements.
State CERCLA reporting concept — Federal Superfund law addresses cleanup liability for hazardous substance releases.
