10 Terminology RTECS Sensitizer Short-term exposure limit Skin SIC Solubility Solvent Specific gravity 1i

11 Terminology Stability Subpart Z Suspect carcinogen Synergism Teratongenic Thermal Threshold Threshold limit value 1j

12 Terminology Time-weighted average Toxic substance Toxicity Vapor Vapor density Vapor pressure Viscosity Volatility End of terminology! 1k

13 Health hazards Acutely toxic Chronically toxic Carcinogenic Mutagenic Teratogenic Sensitizing agent Corrosive Irritant Health hazards cause health effects upon exposure 2a

14 Physical hazards include any chemical that is: Combustible liquid Compressed gas Explosive Flammable Organic peroxide Oxidizer Pyrophoric Unstable (reactive) Water-reactive 2b

15 Hazard communication program Must comply with Hazard Communication Standard - 29 CFR a

16 Hazard communication program Written program must include: a list of hazardous chemicals present in the workplace MSDS labeling system information 3b

17 Hazard communication program Written program must include: employee training information information regarding non-routine hazards methods of informing employers of other workers (contractors) 3c

18 Hazard communication program Written program does not have to be accessible to every work area and every work shift Written program is available to workers upon request 3d

19 Accessing Hazcom documents Workers must know how to obtain, and the location of: the written hazard communications program lists of hazardous chemicals MSDSs 4a

20 Protective measures Work practices Engineering controls Personal protective equipment 5a

21 Material safety data sheets Primary tool for getting detailed chemical information Must be readily available 6a

22 Material safety data sheets include Chemical identity Physical and chemical characteristics Physical and health hazards Primary routes of entry 6b

23 Material safety data sheets include PEL, TLV, other exposure limits Whether it is a carcinogen Precautions for safe handling/use Recommended engineering controls 6c

24 Material safety data sheets include Emergency first aid procedures Date of preparation Name, address, phone number of manufacturer, importer, responsible party 6d

25 Material safety data sheets MSDSs may contain recommendations from ANSI MSDSs also provide information regarding: signs and symptoms of exposure personal protective equipment spill and leak clean-up labeling information 6e

26 Each chemical must have an MSDS MSDS must be available to downstream employers from: chemical manufacturers importers distributors 7a

27 Labeling requirements Labels warn of potential dangers Labels are not intended to be the sole source of information Labels serve as an immediate warning 8a

28 Labeling requirements Labels must be keyed to MSDSs Labels must contain: the identity of the hazardous chemical appropriate hazard warnings the name, address of the chemical manufacturer, importer, other responsible party 8b

29 Labeling requirements Ensure that labels do not come off, become smudged or unreadable For hard-to-label containers, use: signs or placards process sheets, or batch tickets 8c

30 Labeling requirements Be able to quickly identify the general hazard of any material: NFPA system identifies: health hazards flammability hazards reactivity hazards special hazards 8d

31 Labeling requirements Be able to quickly identify the general hazard of any material: HMIS system identifies health hazards flammability hazards physical hazards 8e

32 Hazards of non-routine tasks Know what chemicals you work with and their hazards Know the contents of pipes 9a
