monitoring
Monitoring
  • Employees are able to observe the monitoring.

3a

monitoring7
Monitoring
  • Ongoing monitoring depends upon the following factors:
    • Concentrations at or above the action level, but at or below the 8-hour TWA (annually)
    • Concentrations above the TWA (at least every 6 months)
    • The STEL (as necessary)

3b

monitoring8
Monitoring
  • Monitoring is required after clean-up of spills, leaks, unintentional releases
  • Monitoring may be stopped under some conditions

3c

monitoring9
Monitoring
  • Employees must be told of monitoring results within 15 working days:
    • Individually
    • Group posting
  • Written notification must include corrective actions

3d

monitoring10
Monitoring
  • Additional monitoring may be performed if there is a change in:
    • A process
    • Equipment
    • Personnel
    • Work practices

3e

monitoring11
Monitoring
  • Written exposureplan is required if employees are exposed at or above PEL

work practices
Work practices
  • When working with benzene, workers should never:
    • store or use cosmetics, lip balm
    • drink or smoke

5a

work practices17
Work practices
  • Storage and handling procedures
  • Prohibit sources of ignition
  • Use non-sparking tools

5b

work practices18
Work practices
  • Never incinerate benzene cartridges, tanks, containers
  • Review flammable and combustible liquids regulations - 29 CFR 1910.106

5c

emergency procedures
Emergency procedures
  • Have fire extinguishers available
  • Use foam, CO2, or dry chemical, not water to fight a benzene fire

6a

emergency procedures20
Emergency procedures
  • Flush eyes with water, lifting eyelids
  • Flush skin with water and wash with soap

6b

emergency procedures21
Emergency procedures
  • Move victim to fresh air
  • Do not induce vomiting
  • Get immediate medical attention

6c

emergency procedures22
Emergency procedures
  • Review emergency procedures, including:
    • Written plan
    • Emergency contact phone numbers
    • Emergency contact persons
  • Remove all ignition sources

6d

emergency procedures23
Emergency procedures
  • Evacuate the area
  • Wear appropriate PPE in clean-up area
  • Properly dispose of all waste

PPE
  • Depending on the process, the following PPE might be needed:
    • Impermeable clothing
    • Gloves
    • Goggles
    • Face shields
    • Other protective gear

7a

slide25
PPE
  • Understand the processes for proper:
    • Selection
    • Use
    • Inspection
    • Cleaning
    • Disposal
    • Decontamination

7b

use and limitations of respirators
Use and limitations of respirators
  • Respirators are required:
    • during periods necessary to install or put into effect engineering controls
    • during periods necessary to install or put into effect work practice controls

8a

use and limitations of respirators27
Use and limitations of respirators
  • Respirators are required:
    • where exposure levels are above the TWA or STEL
    • where engineering controls and work practice controls are not sufficient to keep exposures below the TWA

8b

medical surveillance
Medical surveillance
  • Medical surveillance is required for all employees exposed:
    • at or above the action level for at least 30 days
    • at or above the PEL 10 or more days per year
    • to solvents containing more than 0.1% benzene

9a

medical surveillance29
Medical surveillance
  • Exposure thresholds are determined without PPE use

9b

medical surveillance30
Medical surveillance
  • Examinations are:
    • prior to assignment to an area where exposure may be at or above the conditions previously listed
    • annually
    • after exposure in an emergency
    • as a follow-up to previous exams

9c

medical surveillance31
Medical surveillance
  • Examinations are:
    • at intervals recommended by the company physician
    • whenever an employee shows signs and symptoms of toxic levels of exposure

9d

medical surveillance32
Medical surveillance
  • Employees who are required to use respirators at least 30 days per year will have a pulmonary function test every 3 years
  • Medical exams are thorough and emphasize blood chemistry

9e

medical surveillance33
Medical surveillance
  • Related conditions not directly related to benzene may be included in examinations
  • Employees receive a copy of the physician’s written opinion within 15 days after it is received by the company

9f

medical surveillance34
Medical surveillance
  • Records are retained by the employer for the duration of employment plus 30 years

9g
