December 11, 2014 CAER Safety Summit

Overview

Let’s review WHY WHO needs to know this? WHAT’s an emergency? WHERE is a safe distance? WHEN can I respond?

Let’s review WHY?

Required by State and Federal Regulation and by SMR Procedure California Code of Regulations, Title 8,

Section 5192 Federal OSHA 29 CFR 1910.120 Shell Martinez Emergency Manual,

Section 2 Personnel and Responder

SAFETY

WHO needs to know this?

First Responder, AWARENESS level All non-operations field employees

Understand & recognize potential hazards or situations

Knowledge of how to and who to call for help RSL, 3601, 2222, Orange Button on radio, etc.

Get themselves to safe location away from hazard

First Responder, OPERATIONS level Operations personnel in area of expertise

(trained in unit) Respond defensively from a safe distance

WHO needs to know this?

Hazardous Materials Technician Aux Crew, Basic Fire Crew, SHARCs, RATs

when responding under the direction of Incident Commander Respond for the purpose of stopping a leak More aggressive than Operations level May approach the point of release to stop it

Incident Commander / On-Scene Manager Trained individuals

WHAT’s an emergency?

An occurrence which results, or is likely to result, in an uncontrolled release, which may cause high levels of exposure to toxic substances, or which poses danger to employees requiring immediate attention.

WHERE is a safe distance?

WHEN can I respond? When operating under the

direction of the IC / RSL (present at scene), or

RSL has been contacted and is responding. Let RSL know what you’re doing and how you’re doing it.

Responder assumes all responsibilities for appraisal and size-up of scene, and operates from a safe distance. Monitoring of area - toxic, flammable, both? Is it possible that this release may hurt

me? Proper PPE, backup person(s), etc.

RSL / IC approves each case.

Visible Extent of Vapor Clouds

The vapors in vapor clouds aren’t always visible: in fact, many of the vapors of concern to us are invisible

We can see condensate: chilling of water vapor in the atmosphere caused by emissions from evaporating cryogenic liquids (e.g., LPG, anhydrous ammonia, liquid nitrogen, liquid oxygen)

We can see smoke (e.g., emission of finely divided particulate from oils at high temperature)

Visible extent can be larger than flammable or toxic extent (“safe”) Visible extent can be smaller than flammable or toxic extent

(“unsafe”)
