Fall Protection

• Fall protection is a standard designed to reduce or eliminate injuries from falls.

• The standard requires fall protection to be used when a technician needs access, movement, or works at an elevation of 6 feet or higher.

Hoisting Equipment

• Hoisting systems are used to safely raise, lower, and move loads that are too heavy to moved manually.

• The most difficult aspect of the job is estimating the load.

• Loads should be suspended no longer than necessary.

HAZWOPER is categorized as follows:• Emergency Response – first responder awareness

level, first responder operation level, and hazardous materials technicians and specialist level

• Hazardous Waste Operations – Incident command system, scene safety and control, spill control and containment, decontamination procedures, emergency termination, or all clear

• Hazard Protection, Prevention and Control – terms and definitions, PPE levels, identifying hazardous materials and hazards initiating an emergency response, avoiding hazards, entry of hazardous materials into the human body, and use of field monitors and field survey instruments

The HAZWOPER standard defines five levels for emergency responders

• First responder – awareness level• First responder – operations level• Hazardous materials technician level• Hazardous material specialist• On-scene incident commander

First Responder – Awareness Level

The first responder – awareness level is directed at individuals who witness or discover a hazardous chemical release and who have received emergency response training.

First Responder – Operations Level

• When a hazardous chemical release occurs, the process technicians working on the unit specific to the release will attempt to respond.

• It is virtually impossible to pull a highly trained emergency response team who would know the unit a fraction as well as the technicians.

Emergency Response• Emergency response is defined as a loss

of containment of a chemical or the potential for loss of containment that results in an emergency response situation requiring an immediate response.

• Emergency response procedures are applied to every individual working for a company.

Hazardous Waste Operations

• Hazardous waste operations in the CPI involve the use of a complex incident command system. The ICS coordinates all emergency response activity.

• Hazardous waste operations are classified into three categories:

• Small hazards

• Medium-sized hazards

• Large hazards

Scene Safety and Control

• Hot zone - the area around the incident where contamination has occurred.

• Warm zone – used to decontaminate technicians leaving the hot zone.

• Cold zone – a staging area where the incident command post is established.

Spill Control and Containment

Absorbents, adsorbents, curbing and diking, segregated sewers, earthen dams, and fire monitors are devices used to control chemical spills and releases.

Decontamination Procedures

In a decontamination procedure, anything that comes into contact with a hazardous chemical is neutralized in the warm zone.

Hazard IdentificationDuring a chemical release the identification of the material is important, the following procedures must be completed quickly and from a safe distance:– Determine the location of the release.– Analyze the composition of the material.– Identify other characteristics.– Report and discuss with area technicians

and supervisors.

Unit Monitors and Field Survey Instruments

• Draeger pumps are portable vacuum-type devices used to collect a representative gas or vapor sample to check for a known contaminant.

• Explosimeters are used to determine whether there are sufficient concentrations of a combustible gas mixture to produce a fire or explosion.

Cutting, Welding, and Brazing

Produce toxic fumes, generate ultraviolet radiation and electricity, and can easily start a fire.
