Kitchen Fire Extinguisher VR Training: Grease Fires, Class K and the Hood System (OSHA 1910.157)

VR kitchen fire scenario on OSHA 1910.157: grease fire response, Class K extinguishers, the hood suppression pull station, PASS and when to evacuate.

QUICK ANSWER

OSHA 1910.157(g) requires employers who provide portable fire extinguishers for employee use to train employees on the general principles of extinguisher use and the hazards of incipient stage firefighting, at initial employment and at least annually. A VR kitchen fire scenario gives cooks a grease fire they can put out, or fail to, safely.

What the Rule Requires

29 CFR 1910.157, Portable fire extinguishers: where portable fire extinguishers are provided for employee use, the employer must provide an educational program to familiarize employees with the general principles of fire extinguisher use and the hazards involved with incipient stage firefighting, upon initial employment and at least annually. Employees designated to use firefighting equipment must be trained in its use.

The scenario has a fryer fire during dinner rush. A cook tries to throw water on it, a second cook grabs an ABC extinguisher, and the hood system pull station is behind a stack of boxes. The learner must activate the hood system, use the Class K extinguisher and know when to leave.

Hazards in This Scenario

Water on grease causing a fireball
Wrong extinguisher type
Blocked pull stations and extinguishers
Staying too long

The Procedure the Scenario Rehearses

Never use water on a grease fire
Activate the hood suppression system pull station
Use the Class K extinguisher with PASS
Turn off the gas or heat source if safe
Evacuate if the fire grows
Report and keep pull stations clear

Mistakes the Scenario Is Built to Catch

Throwing water on a grease fire
Using ABC first instead of activating the hood system
Not knowing where the pull station is
Fighting a fire past the incipient stage

What VR Does Not Replace

Hands-on extinguisher discharge
Hood system inspection and maintenance
Fire department response

Scope of a One-Scenario Pilot

A pilot builds this scenario as a single module, in Unity or Unreal Engine depending on the visual fidelity the task needs and the headsets on site. It runs on standalone headsets, logs every learner decision, and exports a per-person record for your training file. It is measured against your current method with a test cohort before anything is scaled.

Frequently Asked Questions

What extinguisher is used for a grease fire?

A Class K extinguisher, after activating the hood suppression system.

How often is extinguisher training required?

At initial employment and at least annually, under 1910.157(g)(2).

Can VR replace hands-on extinguisher practice?

It can carry most practice safely. Some employers also do a live discharge.
