Vapor Density >1 = Heavier than air Vapor Density <1 = Lighter than air Flash Point is - Answer -the minimum temperature at which a liquid fuel produces enough vapor to burn momentarily

Fire Point is - Answer -The temperature at which enough vapors are given off to support continuous burning. Ignition (or Auto-Ignition) Temperature is - Answer -The minimum temperature required to initiate or cause self-sustained combustion (burning) IN THE ABSENCE OF ANY SOURCE OF IGNITION Lower Explosive Limit (LEL) - Answer -The percentage of the minimum concentration of vapors in the air necessary to have a fire or explosion. At 100% LEL, there are sufficient vapors in the air for a fire or explosion Upper Explosive Limit (UEL) - Answer -The maximum concentration of vapor in the air, above which a fire or explosion will not occur in the presence of an ignition source. Between the LEL to the UEL is the - Answer -Flammable Range T or F If the time spent in a particular radiation field is doubled, the worker's dose is doubled. and vice versa - Answer -True True or False: If a PROPER shield (such as a particular filter respirator) is placed between the radiation source and a person, the dose will be eliminated or decreased. - Answer -True PEL - Answer -permissible exposure limits: the max airborne concentration of a contaminant to which an employee may be exposed over the duration specified by the type of PEL. TWA (Time Weighted Average) - Answer -An evaluation of exposures that are time-weighted over an established period. It allows the exposure levels to be averaged generally over an eight-hour time period. It must not exceed an 8-hour shift or a 40-hour work week. Action Level - Answer -When exposure reaches 50% of the applicable exposure limit (PEL). Immediately Dangerous to Life or Health (IDLH) - Answer -This is a term which NIOSH defines as an atmosphere in which staying longer than 30 minutes will cause irreversible effects or hinder the worker's ability to exit.

Threshold Limit Value (TLV) - Answer -Refers to airborne concentrations of substances and represents conditions under which it is believed that nearly all workers may be unaffected. Asphyxiants - Answer -Chemicals that interfere with oxygen transport to the body. Irritants - Answer -Substances that can cause discomfort or pain to the eyes, skin, or respiratory system. O2 Deficient atmosphere - Answer -19.5% O2 Deficiency Symptoms Present at - Answer -16% Signs of O2 deprivation - Answer -Impaired attention span, judgment, coordination At O2 Concentrations Less than 16% - Answer -Nausea, Vomiting, Brain Damage, Heart Damage, Unconsciousness, Death Topographic and Physical Hazards - Answer -Holes or Ditches, Slippery Surfaces, Uneven Terrain An Asphyxiating Atmosphere - Answer -üAny space having less than 19.5% O Flammable or Explosive Atmospheres - Answer -Gas or vapor present in concentration greater than 10% of the LFL At what percentage is LFL is considered IDLH in a confined space - Answer -10% At what percentage is LFL is considered IDLH in open air - Answer -25% Combustible gas indicator (CGI) - Answer -A device designed to detect flammable gases and vapors. Also referred to as a flammable gas detector.

Permit-Required Confined Spaces - Answer -- Contains or has the potential to contain a hazardous material

• Contains a material that has the potential for engulfing the entrant
• Entrant could get trapped or asphyxiated by inwardly converging walls or by floors which slope down and taper to a small cross section Sloping/Benching must be used during trenching unless - Answer -Unless less than five feet deep What minimum level of Hazmat PPE is required for an initial on site survey if a haz substance is suspected to be present or unknown - Answer -Level B How many people should make up the initial entry team - Answer -4 personnel: − Two make entry, two as back-up Protection of Entry Personnel - Answer -Decontamination plan should be established and a station set up to prepare for egress and emergencies before entry is made. Monitor the air for IDLH i.e. O deficiency and enrichment and radiation Map should be prepared prior to site entry and updated to reflect - Answer -Changes in site activities or hazards not previously identified. Exclusion Zone - Answer -Where contamination does or could occur Contamination Reduction Zone - Answer -The "warm" zone, transition area between contaminated and clean, Decontamination takes place here Health & Safety Plan HASP - Answer -required by 29 CFR 1910.120 and must be site specific to PPE, Air and Personnel Monitoring, and Emergency Communication If a CGI is calibrated to methane and used to test for a natural gas (methane) leak - Answer -a reading of 50% LEL would mean that half of the methane needed to reach an explosive environment is present in the air

Air containing adequate oxygen must be supplied to the worker using an air line or SCBA under what ambient concentration of O2? - Answer -oxygen levels are lower than 19.5% What device is used to determine the concentration of ionizable vapors in the air? - Answer -PID OSHA requires Medical Records be kept for - Answer -30 Years At what dB level is a hearing conservation program necessary? - Answer -85 dB At what dB is are engineering or administrative controls required? - Answer -90 dB Incident Commander - Answer -The person responsible for all aspects of an emergency response Permeation - Answer -Dissolves or moves through materials at molecular level.
