1
Vinyl Chloride
2
Health hazards Acute (immediate) health effects Inhalation
Direct contact Ingestion 1a
3
Health hazards Chronic (long-term) effects
Raynaud’s syndrome Liver damage Nervous system damage Cancer, especially liver cancer Make effective use of warning labels 1b
4
Permissible exposure limits
No employee may be exposed to vinyl chloride at concentrations greater than 1 ppm TWA No employee may be exposed to vinyl chloride at concentrations greater than 5ppm over any 15 minute period 2a
5
Permissible exposure limits
No employee may be exposed to VC by direct contact with liquid VC 2b
6
Vinyl chloride operations
Areas, processes that use vinyl chloride Handling equipment 3a
7
Vinyl chloride operations
Jobs that involve vinyl chloride activities Operations where exposure to vinyl chloride exceeds PEL 3b
8
Protective measures to prevent exposure
Use exhaust ventilation systems Minimize the release of vinyl chloride Follow proper operating procedures 4a
9
Protective measures to prevent exposure
Wear required personal protective equipment Keep containers closed, protected from damage, properly stored 4b
10
Protective measures to prevent exposure
Establish regulated areas where concentrations are in excess of PEL 4c
11
Respiratory protection
Required whenever engineering and work practice controls do not reduce exposure levels below the PEL Use engineering and work practice controls to reduce exposure levels to the lowest practical level 5a
12
Respiratory protection
Select the type of respirator based upon atmospheric concentration of vinyl chloride Limitations of respiratory equipment 5b
13
Exposure monitoring Initial monitoring to determine if exposures are above action level (0.5 ppm TWA) Test after changes in production, processes, or controls 6a
14
Exposure monitoring Test if any employee may be exposed above the action level Repeat the monitoring if any exposures are above the action level 6b
15
Exposure monitoring Repeat monitoring at least monthly if exposures are above the PEL Repeat monitoring at least every three months if exposures are above the action level 6c
16
Exposure monitoring Monitoring can only be discontinued after two consecutive tests, made five days apart, show exposure is at or below the action level 6d
17
Exposure monitoring Monitoring methods must meet accuracy standards
Employers must notify employees in writing within 10 working days if exposure is in excess of PEL 6e
18
Exposure monitoring Maintain monitoring records according to 29 CFR 6f
19
Medical surveillance Available to employees having exposure in excess of the action level Exams must be conducted under the supervision of a licensed physician 7a
20
Medical surveillance Exams are without cost to employees
Exams consist of: general physical exam review of employee’s medical history specific blood tests 7b
21
Medical surveillance Medical surveillance must be started when:
an employee is initially assigned to work where exposure exceeds the action level operations change so that exposure levels increase to above the action level 7c
22
Medical surveillance Medical surveillance must be started when:
an employee is exposed to vinyl chloride as a result of an emergency Exams are repeated annually for most employees exposed above the action level 7d
23
Medical surveillance Physician issues a statement of the employee’s suitability for continued exposure to vinyl chloride Employee receives a copy of the statement 7e
24
Emergency situations Employees engaged in hazardous operations are required to use respiratory protection and protective clothing Emergencies must be reported to OSHA within 24 hours 8a
25
Emergency situations A written operation plan must be developed for each facility storing, handling, using vinyl chloride Remember that vinyl chloride is flammable; consult MSDSs 8b
26
Training Review paragraphs (a) through (o) of 29 CFR 9a
