13. Exposure monitoring to determine employee exposures
Affected employees and their representatives have the right to observe any exposure monitoring
Affected employees must be informed of monitoring results within 5 working days of receipt 7b

14. Exposure monitoring to determine employee exposures
Within 15 working days of receipt of results, employees must be informed of the corrective actions being taken to reduce any exposures to below the PEL or STEL 7c

15. Engineering controls limit exposure to BD

16. Work practices and procedures
Never eat, drink, or smoke where BD is used, stored, or handled
Do not keep food, beverages, or smoking materials in these areas 9a

17. Proper storage and handling
Tightly close cylinders and containers
Protect cylinders from damage
Outside or detached storage is preferred
Inside storage should be in a cool, dry, well-ventilated, noncombustible area 9b

18. Proper storage and handling
BD in storage should be checked for proper inhibitor content, for self-polymerization, and for formation of peroxides when in contact with air and iron
Avoid contact with copper and copper alloys. Explosive copper compounds can form 9c

19. Proper storage and handling
Store away from flammables, combustible materials, and oxidizing materials
Store away from sources of ignition
Store cylinders vertically 9d

20. Work practices and procedures
All electrical installations and equipment used in areas where BD is present must be rated for a Class I hazardous location
Waste BD is classified as a hazardous waste due to its flammability characteristics
Other safe work practices at our facility 9e

21. Regulated area

11c

25. Personal protective equipment (PPE) requirements
Necessary if the use of engineering and work-practice controls does not reduce exposure to levels at or below BD’s PELs
Employees are required to use it properly
Our PPE requirements 12

26. Respiratory protection required
When exposure exceeds 1 ppm as an 8-hour TWA or 5 ppm as a 15-minute STEL
During installation or set up of engineering and work-practice controls

29. Medical screening and surveillance program schedule
When exposure to BD is at or above the action level on 30 or more days a year
When exposure to BD is at or above the PELs for 10 days or more a year
Following an emergency situation
14a

30. Medical screening and surveillance program schedule
