23
Q

How often are medical exams required

A

once a year

24
Q

When must workers have medical evaluations

A

Required whenever worker is issued a negative-pressure respirator

25
Q

When are medical exams required

A

whenever work is at or above the 8 hour TWA limit or the Excursion limit for more than 30 days in a year

26
Q

What is the 8 hour TWA

A

0.1 fibers per cubic centimeter. means that 0.1 f/cc is the highest average number of fibers in the air which OSHA law allows a worker to be exposed to over an 8 hour time period.

27
Q

What is the excursion limit

A

1.0 fiber per cubic centimeter in 30 minutes. Protects from a large amount of exposure in a short period of time.

28
Q

How many parts are there to a yearly asbestos medical exams?

A

3.Questionnaire, Pulmonary Function Test, General Exam. Could include but not required: chest x-ray, EKG

29
Q

What does the first yearly exam establish

A

a baseline

30
Q

Medical Records

A

Employer must give you a copy within 30 days, must keep records for 30 years after you leave the job

31
Q

What is a respirator

A

A mask that filters the air in the room or supplies clean air from outside the room

32
Q

List the respirators

A

R100 - resistant to oil
N100 - Not resistant to oil
P100 - oil proof
Magenta filter - stacked

33
Q

What are the 4 things that you need to know to choose a respirator

A

The amount of asbestos in the air
The Permissible Excursion Limit
The Assigned Protection Factor
The Maximum Use Concentration

34
Q

what is PEL

A

Permissible excursion limit: the amount of asbestos in the air that OSHA allows you to be exposed to. There are 2: 8 hour TWA and the Excursion Limit (EL)

35
Q

What is APF

A

assigned protection factor: the degree of protection a respirator

36
Q

MUC

A

maximum use concentration - the largest amount of asbestos in the air of the work place that a respirator is good for

37
Q

What is the formula for MUC

A

Maximum Use Concentration = TWA x Assigned Protection Factor

38
Q

Respirator below 1 fiber/cc

A

1/2 mask

39
Q

Respirator above 1 fiber/cc

A

need one with a higher APF

40
Q

1/2 mask APF

A

APF 10. If there are 10 f/cc in the air, there is 1 f/cc in the mask

41
Q

Full face air purifying or PAPR with half mask APF

A

APF 50.

42
Q

PAPR continuous flow or pressure demand supplied air with full face

A

APF 1000

43
Q

what is CL

A

Clearance level: when the area is clean 0.01 or 1/100 f/cc

44
Q

What is a negative pressure respirator

A

When you breathe in it makes a suction

45
Q

Respirator bill of rights

A

Must assign one person to be in charge of the respirator protection program
Must have written procedures for choosing and using respirators
Employer must check the whole respiratory protection program regularly
Employer must provide medical evals
Must have you trained about respirators
Must provide NIOSH approved respirators

46

A

Encapsulation
Enclosure
Removal
Repair
O&M

47

regulates all asbestos response control methods in public or private, elementary or secondary schools. K-12

48
Q

MNOSHA

A

regulates all worker exposure to asbestos

49
Q

Class I Asbestos Work

A

Any work to do with the removal of asbestos containing TSI and sprayed or troweled on SM

50

A

Any work to do with the removal of asbestos material which is NOT TSI or SM. Floor tiles, roofing, shingles, siding, etc

51
Q

52
Q

MPCA

A

MN Pollution Control Agency, regulates the removal, transportation, and disposal of asbestos when the amount of RACM to be removed is at least 260 linear feet on pipes, 160 sq feet on other facility components, or if the linear or square footage cannot be measured, 35 cubic feet

53
Q

RACM

A

is greater than 1%, friable, non-friable which has become friable, non-friable made friable through sanding, grinding, etc. non-friable becomes friable through demo
