Title: Cadmium


1
Cadmium
2
Regulated areas
  • Regulated areas are created where employees are
    exposed to concentrations above the PEL
  • Respirators are provided for employees who must
    access regulated areas

1a
3
Regulated areas
  • You must wear respirators when required to do so
  • What job titles/functions are allowed access to
    restricted areas
  • Tour of regulated areas

1b
4
Requirements
  • Substance safety data sheet (Appendix A)
  • Substance technical guidelines for cadmium
    (Appendix B)

2a
5
Requirements
  • Employers are required to control exposures to
    cadmium
  • Airborne concentrations must not exceed the
    action level or PEL

2b
6
Monitoring
  • Methods of detecting the presence or release of
    cadmium
  • Monitoring must be made available for employees
    to observe

3a
7
Monitoring
  • If monitoring shows exposure at or above the
    action level, monitoring must be done
  • at least every six months
  • when there are changes to personnel, processes,
    or controls
  • Lunchrooms are monitored and kept below the
    action level

3b
8
Monitoring
  • Employees have a right to be notified in writing
    of monitoring results within 15 working days
  • Written notification must include corrective
    actions

3c
9
Physical hazards
  • Flammable and explosive in powder form
  • Spontaneous combustion of dust

4b
10
Physical hazards
  • Sensitive to reaction with
  • oxidizers
  • metals
  • hydrogen nitrite
  • zinc
  • selenium
  • sulfur dioxide
  • tellerium

4c
11
Physical hazards
  • Fire hazard when exposed to these
    chemical/substances
  • oxidizers
  • metals
  • hydrogen nitrite
  • zinc
  • selenium
  • sulfur dioxide
  • tellerium

4d
12
Physical hazards
  • Fight fire with
  • dry sand
  • dry dolomite
  • dry graphite
  • sodium chloride
  • Do not use water, foam, carbon dioxide or Halons

4e
13
Acute health hazards
  • Skin irritation
  • Eye irritation
  • Inhalation

4f
14
Acute health hazards
  • Ingestion
  • Observable effects

4g
15
Chronic health hazards
  • Carcinogen
  • Kidney damage
  • Respiratory damage

4h
16
Chronic health hazards
  • Reproductive health changes
  • Mutagenic
  • Tumorigenic

4i
17
Work practices
  • Engineering controls and work practices are
    primary methods of control
  • Do not shake, blow, or use any other means to
    clean clothing, that would cause cadmium to
    become airborne

5a
18
Work practices
  • Rotation of work duties is not a valid method of
    compliance
  • Keep work surfaces free of cadmium
  • Clean up spills

5b
19
Work practices
  • Use HEPA-filtered vacuuming methods
  • Compressed air for cleaning should be used only
    with proper ventilation

5c
20
Work practices
  • Be aware of washing facilities
  • Respirators must be used where required

5d
21
Emergency procedures
  • Written emergency action plan
  • First aid measures
  • Eyes
  • Skin
  • Inhalation
  • Ingestion

6a
22
Emergency procedures
  • Emergency evacuation

6b
23
Emergency procedures
  • Cadmium metal dust is a fire hazard and reacts
    with
  • oxidizers
  • acids
  • ammonia
  • selenium
  • sulpher dioxide

6c
24
Personal protective equipment
  • Required for employees exposed above the PEL or
    where skin or eye irritation is associated with
    exposure
  • Coveralls
  • Gloves, head coverings, and boots
  • Face shields, vented goggles

7a
25
Personal protective equipment
  • Selection, use, limitations, inspection
  • Cleaning and disposal
  • Changing rooms and storage

7b
26
Personal protective equipment
  • Repair/replace defective equipment
  • Decontamination
  • Any employee whose clothing is contaminated must
    immediately remove clothing and shower

7c
27
Personal protective equipment
  • Washing contaminated clothing
  • Splashproof eye or dust-resistant goggles

7d
28
Limitations of respirators
  • Respirators are a critical element of the
    training program
  • Employees have a duty to wear respirators
  • Proper selection, donning, doffing, use,
    limitations, decontamination and storage

8a
29
Medical surveillance
  • Required for all employees who are, or may be
    exposed at or above the action level
  • Medical examinations are thorough

9a
30
Medical surveillance
  • Employees may be medically removed from duty if
    testing/monitoring detects ongoing problems

9b
31
Medical surveillance
  • Copies of physicians written opinions
  • Records are retained for the duration of
    employment plus 30 years

9c
32
Medical surveillance
  • Examinations will be conducted
  • within 30 days of assignment
  • at least annually
  • whenever an employee is exposed above the action
    level
  • following an exposure
  • whenever an employee shows signs/symptoms of
    exposure

9d
33
Medical surveillance
  • Examinations will be conducted
  • for a year after an employee stops working with
    cadmium
  • at termination of employment
  • Examinations may be scheduled if biological
    monitoring detect high levels of cadmium

9e
34
Labeling system
  • Post and maintain signs around regulated areas
  • Report faded or missing signs

10a
35
Labeling system
  • Labels are required on all containers similar to
    the following
