Personal Protective Equipment (PPE)

S3 — Operations: Core

Why this chapter matters

PPE selection is an operations/technician function; awareness identifies suggested levels from ERG but does not dress for entry.

Learning objectives (6)

  1. Match ERG PPE guidance to level names — Translate ERG suggestions into A-D vocabulary for communications.
  2. Explain Level A — Fully encapsulating suit with SCBA for highest respiratory and skin protection.
  3. Explain Level D — Work uniform minimum; no chemical protection.
  4. Define permeation vs degradation — Permeation is breakthrough; degradation is physical breakdown of material.
  5. Awareness PPE limit — Do not don entry ensemble or cross hot line without qualification.
  6. Use NIOSH Pocket Guide PPE section — Confirm respiratory and skin protection when chemical ID known.

Chapter outline

  1. CPC and respiratory protection families

Quick fire sample (15 of 82 on Quiz Me)

Level A is used when:
  1. Highest skin and respiratory protection needed
  2. No chemical hazard exists
  3. Only paperwork is required
  4. Hospital menus are selected
Awareness responders should:
  1. Not dress for hot-zone entry
  2. Always use Level A for odors
  3. Patch valves without training
  4. Skip command notification
Permeation means:
  1. Chemical passes through intact CPC over time
  2. Suit color fades only
  3. Gloves never fail
  4. SCBA is unnecessary
IDLH atmospheres require:
  1. SCBA, not APR alone
  2. Level D only
  3. No respiratory protection
  4. Street clothes
Level D provides:
  1. No chemical protection
  2. Encapsulation and SCBA
  3. Highest vapor protection always
  4. Mandatory Level A equivalent
ERG PPE guidance should be:
  1. Communicated to technicians, not self-assigned by awareness
  2. Ignored
  3. Used to authorize untrained entry
  4. Replaced by social media
