OSHA 40 HAZWOPER TERMS FOR EXAM year the osh act was written 1970 under the Dept of Labor Detailed Site-Specific Hazards Assessment must be performed according to what federal regulation? 29 CFR 1910.120 29.CFR.1910.1200 Requires employees to 1.Adopt a written hazard communication program 2.Keep SDS for chemicals on the site 3.Provide education and training to employees T or F: Chemical Safety Data Sheets (SDS) must be prepared by every chemical manufacturer True! New system that replaced the original HAZCOM Material Safety Data Sheet (MSDS) System GHS Global Harmonization System, simply called Chemical Safety Data Sheets (SDS). OSHA and EPA not interchangeable in their roles (what are their roles?) Protect human health and safeguard the environment (air, water and land). General Site Workers must have a minimum of ??? 40 hours of off-site instruction. General Site Workers and Treatment, Storage, and Disposal (TSD) workers must receive ??? hours of refresher training annually. 8 Hours What Part under 29 CFR regulates EMERGENCY RESPONSE to hazardous substance releases 29 CFR 1910.120 ==>(Q)<== What is the name of the standard that regulates Hepatitis B, HIV, AIDS Occupational Exposure to Bloodborne Pathogens 1910.1030 What is a hazardous substance? ANY substance designated as hazardous under ANY federal regulation. All matter can exist in three different physical states: Solid Liquid Gas DEPENDING ON Depends on temperature and pressure What is Specific Gravity (SG) ratio of mass of substance to mass of volume of water SG < 1.0 will float in water SG > 1.0 will sink in water TWA (Time Weighted Average) 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 When exposure reaches 50% of the applicable exposure limit (PEL). Immediately Dangerous to Life or Health (IDLH) 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) Refers to airborne concentrations of substances and represents conditions under which it is believed that nearly all workers may be unaffected. Asphyxiants Chemicals that interfere with oxygen transport to the body. Irritants Substances that can cause discomfort or pain to the eyes, skin, or respiratory system. O2 Deficient atmosphere 19.5% O2 Deficiency Symptoms Present at 16% Signs of O2 deprivation Impaired attention span, judgment, coordination At O2 Concentrations Less than 16% Nausea, Vomiting, Brain Damage, Heart Damage, Unconsciousness, Death Topographic and Physical Hazards Holes or Ditches, Slippery Surfaces, Uneven Terrain An Asphyxiating Atmosphere üAny space having less than 19.5% O2 Flammable or Explosive Atmospheres Gas or vapor present in concentration greater than 10% of the LFL At what percentage is LFL is considered IDLH in a confined space 10% At what percentage is LFL is considered IDLH in open air 25% Combustible gas indicator (CGI) A device designed to detect flammable gases and vapors. Also referred to as a flammable gas detector. Permit-Required Confined Spaces - 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 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 Level B How many people should make up the initial entry team 4 personnel: − Two make entry, two as back-up Protection of Entry Personnel 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. O2 deficiency and enrichment and radiation Map should be prepared prior to site entry and updated to reflect Changes in site activities or hazards not previously identified. Exclusion Zone Where contamination does or could occur Contamination Reduction Zone A work uniform. When should a decon plan be put in place in the site response process? Before any personnel or equipment enter potential hazardous areas What can improper decon procedures can lead to Chemical reactions due to incompatibility. Release of toxic or flammable vapors. Degradation of PPE. Some decon scenarios require personnel to wear PPE at the same level as those entering Exclusion Zone (EZ) exceptions to this rule allow for??? decon personnel to wear level just below those entering EZ. Physical evidence may indicate that a HAZMAT incident is escalating −Frost forming near a leak (auto refrigeration) −Deformed containers (bulging drum) -"Pinging" vessel sounds Procedures to remember when opening haz waste/pressurized containers Do not lean over bung when opening drum Continuously monitor during opening procedure Decon equipment after each use to avoid mixing T or F: Under DOT the transporter is responsible for any kind of discharge during shipment True and if the spill exceeds reportable quantities the NRC must be notified immediately. Under DOT discarges of extremely hazardous substances require Immediate notification of local and state emergency planning committees. DOT requires a written report of the incident ERG (Emergency Response Guidebook) What do you refer to when responding to an incident involving Hazmat or hazardous materials? What are DOT Railroad shipping papers called? A Consist What are DOT papers found inside a trailer? A Manifest or a Bill of Ladden
