incident. Be able to read placards and labels. Able to read and interpret the DOT book. Able to implement site security and control. Understand the basics of an Emergency Response

Plan

Role of First Responder - Awareness

29 CFR 1910.120(q)

• Likely to witness or discover release.

• Trained to initiate emergency response.

• Take no further action .

FIRST RESPONDER AWARENESS LEVEL

• Understand what hazardous materials are and their risks in an incident.

• Understand the potential outcome of an emergency created when hazardous materials are present.

• Ability to recognize the presence of hazardous materials in an emergency.

• Ability to identify hazardous materials if possible

• Role of the First Responder in the Emergency Response Plan including site security & control and DOT’s Emergency Response Guidebook.

• Ability to realize the need for additional resources and to make appropriate notification to communication center.

HISTORY Superfund Amendments and

Reauthorization Act of 1986 (SARA)– allocated funds to develop health and safety

training for workers involved in transportation, storage, or disposal of hazardous waste.

Hazard Recognition

Definitions

Hazardous substance: “OSHA”

A substance included as a hazardous material by DOT and as a hazardous waste by EPA

Hazardous Waste - EPA

Poses unreasonable risk to health, safety or property when transported in commerce for the purposes of treatment, storage, or disposal as waste

Hazardous Material - DOT

Any substance or material in any form or quantity which poses an unreasonable risk to safety and health and property when transported in commerce

Chemical Hazards Flammable Corrosive Reactive Toxic Sudden Release of Pressure (explosion)

– detonation and deflagration

– body response at time of exposure, typically a high concentration, or a few days after exposure.

Chronic– body response takes a long time after

repeated or prolonged exposures.

EMERGENCY RESPONSE PLANS

Elements:

• Emergency escape procedures & route designations

• Procedures for employees who stay to operate critical operations before they evacuate.

• Accountability procedures for all on-site personnel.

Elements continued:

• Rescue and medical responsibilities

• Fire and emergency reporting

• Emergency call list for notification and assistance

• PPE & emergency equipment

EMERGENCY RESPONSE PLANS

RISK ASSESSMENT

•Probability of an unwanted event.

•Hazards associated with event.

•Control measures.

Hierarchy of Controls:

A. Engineering

B. Administrative work practices

C. Respirators and PPE

Engineering Controls Pressurized cabs on heavy machinery Control booths Remotely operated material handling

equipment

Work Practices Remove all non-essential personnel Wetting down dusty operations Locating employees upwind of possible

hazards

The potential risk from the many hazardous properties of any particular material will vary depending on the conditions during the emergency.

In addition to being able to recognize what has already happened in an emergency, it is necessary to recognize the potential for other problems i.e. a small fire could develop into an explosion.

For an Emergency Response Plan to be effective, it requires

pre-planning Training or exercise (Table Top) critique/follow-up.

Additional Resources

A first responder must become familiar with the capabilities and limitations of the emergency response team in order to determine the need for additional help or resources.

SITE SECURITY AND CONTROL

• Safe distances

• Evacuation & isolation

• Places of refuge

Site Security & Control cont.

• point of entry

• site maps

• area entry logs

• boundaries

Site Security and Control cont.

• Accessibility of potential routes

• Multiple evacuation routes

• Mark evacuation routes

• Make escape routes known to all

COMMUNICATIONS

----First Responder - Awareness has the ability to make appropriate notifications to the communications center.
