Emergency + Energy Control

Quick, calm, and clear actions save the day. Post this in a visible spot. Keep it updated. Fill in the blanks so anyone can act fast.


1) Fire Extinguishers — Types & Locations

  • Map/label each extinguisher and the hazards nearby.
  • Common types:
    • A: Paper/wood
    • B: Flammable liquids
    • C: Electrical
    • ABC: Multi-purpose
  • Fill in:
    • Extinguisher #1 (Type): __________ Location: ____________________ Nearest hazard: __________
    • Extinguisher #2 (Type): __________ Location: ____________________ Nearest hazard: __________
    • Extinguisher #3 (Type): __________ Location: ____________________ Nearest hazard: __________
  • Notes:
    • Keep paths clear. Mount at visible height.
    • If fire is bigger than a trash can, evacuate and pull alarm.

2) Eyewash & Safety Shower — Path + Check Time

  • Fastest path from work area to eyewash/shower: ______________________________
  • Backup path (if blocked): _________________________________________________
  • Door(s)/gate(s) to pass through: ___________________________________________
  • Weekly function check completed on: ___________________ by: ________________
  • Use tips:
    • Eyewash: Flush eyes for a full 15 minutes. Hold lids open. Remove contacts.
    • Shower: Pull handle, remove contaminated clothing, rinse 15 minutes.

3) First Aid Kit — Location & Reporting Steps

  • First aid kit location: _______________________________________________
  • AED (if available) location: __________________________________________
  • After any injury, do this:
    1. Make area safe. Stop bleeding, protect airway, call for help.
    2. Notify supervisor: ___________________ (phone/ext): _________________
    3. Record incident in system/form: ____________________________________
    4. If medical care needed, arrange transport and bring SDS if chemical exposure.
    5. Restock kit after use. Note items replaced: __________________________

4) Emergency Contacts (Post in Order of Use)

  • Internal emergency line: __________________
  • Security/front desk: ______________________
  • Site EHS/Safety lead: _____________________ Phone: ____________________
  • On-call maintenance/utility: ______________ Phone: ____________________
  • External emergency (911 or local): _________ Address to give: __________________________
  • Nearest hospital/urgent care: __________________________________ Phone: __________

5) De‑Energize (Generic 6‑Step Checklist)

Use this for any equipment before service or unjamming. When in doubt, stop and ask.

  • Verify: Identify the exact equipment, energy sources, and hazards (electrical, hydraulic, pneumatic, gravity, springs, thermal, chemical).
  • Isolate: Turn off, open disconnects/valves, block movement, set to safe state.
  • Lock/Tag: Apply personal lock(s) and tag(s) to each isolation point. One person, one lock.
  • Release Stored Energy: Discharge capacitors, bleed pressure, lower/secure loads, vent lines, drain, neutralize.
  • Verify Zero: Try start (test) controls, meter/test for zero energy, check pressure/temperature gauges.
  • Communicate: Tell affected workers. Post status. Hand off only after group review and removal of personal locks by their owners.

Notes:

  • Use the written energy control procedure if one exists for this machine.
  • If energy cannot be fully isolated, use alternative controls approved by EHS.

6) Post‑Incident Debrief Prompts (Same Shift, While Fresh)

  • What happened? In one sentence: ___________________________________________
  • What was the immediate cause (trigger)? ____________________________________
  • Any injuries or exposures? Who/what was affected? ___________________________
  • What helped? (PPE, training, tools, layout): ________________________________
  • What didn’t help? (confusing steps, blocked access, missing gear): ___________
  • What will we change now? (procedures, signage, training, equipment): ________
  • Who owns each action and by when? _________________________________________

Quick Reminders

  • Stay low if there’s smoke. Close doors behind you.
  • Don’t guess on chemicals—check the SDS.
  • If you feel unsafe: stop, step back, and call for help.

Stay ready. Fill this card, post it, and review it at the start of each shift.
