2
Prevent injuries or deaths from: Violent chemical reactions, fires, explosions Burns, irritation, trouble breathing, nausea, diseases Manufacturers, importers: Classify chemical hazards Provide labels, safety data sheets (SDSs) 1a
3
Air monitoring equipment Appearance, odor Physical, chemical characteristics Unknown chemicals to be considered hazardous 2a
4
Chemical manufacturers or importers must classify chemicals according to the physical and health hazards A chemical can have both physical and health hazards 3a
5
1. Explosives 2. Flammable gases 3. Flammable aerosols 4. Flammable liquids 5. Flammable solids 6. Oxidizing liquids 7. Oxidizing solids 8. Oxidizing gases 9. Self-Reactive substances 10. Pyrophoric liquids 11. Pyrophoric solids 12. Self-heating substances 13. Organic peroxides 14. Corrosive to metals 15. Gases under pressure 16. Substances which, in contact with water emit flammable gases
6
Pyrophoric gas - spontaneously ignites at 130°F or below Combustible dust - build-up can ignite if suspended in air in confined area ◦ Grains, sugar ◦ Charcoal, soot ◦ Chemicals (sulfur) ◦ Metals (magnesium, aluminum) ◦ Plastics, resins 4b
7
Acutely toxicity Skin corrosion or irritation Serious eye damage or irritation Respiratory or skin sensitization Germ cell mutagen Carcinogenicity Reproductive toxin Target organ systemic toxin ◦ Single exposure ◦ Repeated exposure Aspiration hazard
8
Engineering controls Administrative work practice Enclosing operations Ventilation equipment Substituting less hazardous chemicals Safe procedures Safer chemical handling procedures 7a
9
Always use in plant Chemical-resistant: ◦ Goggles ◦ Face shields ◦ Gloves ◦ Boots ◦ Coveralls ◦ Aprons ◦ Respirators Do not use damaged, malfunctioning PPE 8b
10
Chemical emergencies can involve fires, explosions, burns, asphyxiations Unknown chemicals are considered to be hazardous Emergency responders manage: ◦ Releases of unknown chemicals ◦ Any potentially dangerous release Others go to safe area, report emergency 9a
11
Check the SDS Report overexposures to any chemical Get prompt first aid, medical attention Contact with corrosive, irritating chemicals: Use emergency eyewash, showers Flush eyes/skin with water 10a
12
Overexposure from breathing vapors, gases, aerosols, fumes, dust: Move victim to safe area with fresh air Get emergency medical assistance Ingesting chemicals: Call poison control center, emergency medical responders Have information from SDS available Only induce vomiting or give water if advised by a medical provider 10c
13
OSHA’s HazCom standard includes requirements for: Chemical classification Safety data sheets (SDSs) Labeling Written HazCom program Employee information, training Provisions for trade secrets Not required if handling closed containers 11a
14
Labels warn of potential dangers Labels are not intended to be the sole source of information Labels serve as an immediate warning Containers need labels Pipes, fuel tanks, engines are not containers 12a
15
While HazCom 2012 is phased in, you will still see labels meeting previous rule: Identity of hazardous chemical Appropriate hazard warnings Name and address of manufacturer, importer, or other responsible party 12b
16
13b
17
Written HazCom program: Labels, warnings Safety data sheets (SDSs) Employee information,training List of hazardous chemicals How employees learn hazards of non-routine tasks Hazards of chemicals in unlabeled pipes 11c
21
Hazards without symbols (Label says warning)- Simple asphyxiant: Hazard statement = “May displace oxygen and cause rapid suffocation” Combustible dust: Hazard statement = “May form combustible dust concentrations in air” OSHA-defined hazards - Pyrophoric gas: Flame pictogram Signal word = “DANGER” Hazard statement = “Catches fire spontaneously if exposed to air” 13f
22
Rely on labels on shipped containers Re-label if label falls off Re-label if label cannot be read 14a
23
Transferring hazardous chemicals to another container: Must label container if another person will use it Must label container if it is available during another shift Individual stationary containers (i.e., tanks) may use: Signs Placards Batch tickets Operating procedures These alternatives must provide the same information as would a label 14b
24
NFPA system identifies: ◦ Health hazards - Blue ◦ Flammability hazards - Red ◦ Reactivity hazards - Yellow ◦ Special hazards - White Hazard severity (0 to 4): ◦ 0 = none ◦ 4 = severe 14e
25
HMIS system identifies: ◦ Health hazards - Blue ◦ Flammability hazards - Red ◦ Physical hazards - Orange ◦ Personal protection - White Hazard severity (0 to 4): ◦ 0 = minimal ◦ 1 = slight ◦ 2 = moderate ◦ 3 = serious ◦ 4 = severe 14f
26
The Globally Harmonized System of Classification and Labeling of Chemicals (GHS) ◦ It is an internationally agreed-upon system, created by the United Nations. ◦ It is designed to replace the various classification and labeling standards used in different countries by using consistent criteria for classification and labeling on a global level. ◦ It established the use of the Safety Data Sheet -SDS that will replace the MSDS. 15a
27
Chemical fact sheets Provided by chemical suppliers Employer keeps them up to date Must be in English Immediately available Report missing SDSs 15a
28
1 Identification 2 Hazard identification 3 Composition 4 First Aid 5 Fire Fighting 6 Accidental release 7 Handling/ Storage 8 PPE requirements 9 Properties 10 Stability/reactivity 11 Toxilogical info 12 Ecological info 13 Disposal 14 Transport 15 Regulatory 16 Other notes
29
Use: Verify label information PPE recommendations Symptoms, health effects First aid Emergency procedures PPE recommendations Symptoms, health effects First aid Emergency procedures 15b
30
Being replaced with SDSs MSDSs include: ◦ Chemical Identity and characteristics, hazards, routes of entry, exposure limits, carcinogen status, precautions, control measures, First aid procedures, date of production, manufacturer identity ◦ Can include other things, do not have a specific order and can be confusing at times 17a
