(24 cards)
NFPA 1981
Standard on Open-Circuit Self-Contained Breathing Apparatus (SCBA) for Emergency Services
OSHA standard states that all employees engaged in emergency response who were exposed to hazardous substances
Shall wear a positive-pressure SCBA
The IC is ____ to ensure the use of ____
Required; SCBA
NFPA 1970
Standard on Protective Ensembles for Structural and Proximity Firefighting, Work Apparel and Open-Circuit Self-Contained Breathing Apparatus (SCBA) for Emergency Services, and Personal Alert Safety Systems (PASS)
When wearing street clothes and normal work uniforms _____ is the best level of protection
Distance from the hazard
Structural firefighting gear is primarily intended to protect the wearer from ______
Thermal and mechanical hazards
_______ are available to aid responders and matching the anticipated chemical hazard to the resistance characteristics of the garment
Manufacturer compatibility charts
Chemical-resistant material
Fabric specifically designed to inhibit, or resist the passage of chemicals into and through the material by process of penetration, permeation, or degradation
Penetration
The movement of a material through a suit’s closures, such as zippers, buttonholes, seams, flaps, or other design features of chemical-protective clothing, and through punctures, cuts, and tears
Permeation
The chemical action of involving the movement of chemicals, on a molecular level through the intact material
Degradation
A chemical action involving the molecular breakdown of a protective clothing, material or equipment due to contact with a chemical
Visible signs include charring, shrinking, swelling, color changes, or dissolving
The “best” level of protection is one that
Is most appropriate for the hazard and the mission
According to the OSHA HAZWOPER regulation, level ____ is the minimum level of protection to be worn when operation in an unknown environment
B
The primary role of the medical monitoring station is to evaluate the status of _____
The entry team, the backup team, and those personnel assigned to decontamination duties
A hand on top of the head making a tapping motions indicates
I’m okay
Hands across the throat indicate
Air problems
Hands over the head in a waving motion, or both hands tapping the head indicates
Trouble
Level A ensemble
Personal protective equipment, consisting of a totally encapsulating suit that includes a self-contained breathing apparatus, and that provides the highest level protection against vapors, gases, mists, and even dusts
Level B ensemble
Personal protective equipment, consisting of a single- or multi-piece chemical protective garment, boots, gloves, and a self-contained breathing apparatus, which is used when the type and atmosphere concentration of substances require a high level of respiratory protection, but a moderate level of skin protection
Level C ensemble
Personal protective equipment, consisting of a NIOSH-approved CBRN air-purifying respirator or powered air-purifying respirator, which is used when the type of airborne substance is known, the concentration is measured, the criteria for using an air-purifying respirator are meant, and skin and eye exposure is unlikely
Level D ensemble
Personal protective equipment typically consisting of coveralls, work, shoes, hard hat, gloves, and standard work clothing, which is used when the atmosphere contains no known hazard, and work functions preclude splashes, immersion, or the potential for unexpected inhalation of or contact with hazardous levels of chemicals
Liquid splash-protective ensemble
Compliant protective clothing and equipment products that when worn together provide protection from some, but not all, risks of hazardous materials/WMD incident operations involving liquids
Vapor-protective ensemble
Multiple elements of compliant protective clothing and equipment that when worn together provide protection from some, but not all, risks of vapor, liquid, splash, and particulate environments during hazardous materials/WMD incident operations
NFPA 1990
Standard for Protective Ensembles for Hazardous Materials and CBRN Operations
