”Instant Reading” Air Sampling
Detector tube air sampling is a quick way to determine the amount of a
chemical in a work area. A Sensidyne Gas Detection Pump with the correct
Sensidyne Detector Tube can be used to detect a number of chemicals. These
tubes can be used to get a snapshot of the air contaminants in a work area.
One tube is used for each potential chemical contaminant in the air.
The Sensidyne colormetric detector tubes can used to
determine concentrations of the known air contaminants. A color change in
the detector tube is indicated. The length of the stain is used to get a
concentration by comparing it to a scale which is etched on the tube.
This method is quick evaluation for screening the
amount of chemical in the air. It is typically used to measure worst case
scenarios to determine if additional sampling is necessary. To obtain an
OSHA shift long chemical exposure assessment, air monitoring with a pump
would be a better solution.
Here is a list a few of the chemicals that we can
sample with a detector tube.
Chemical Measuring
Range TLV/TWA*
Ammonia 5 – 260 ppm **
25 ppm
Carbon Monoxide 1 – 50 ppm
25 ppm
Chlorine 0.1 – 10 ppm
0.5 ppm
Hydrogen Sulfide 1 – 60 ppm
10 ppm
LP Gas 50 – 1,000 ppm
1,000 ppm
Methylene Chloride 10 – 1,000 ppm
50 ppm
Nitrogen Dioxide 0.5 – 30 ppm
3 ppm
The cost for sampling with this method for up to 10
samples per chemical is approximately $900 with an e-mailed air monitoring
report. Travel outside of the Phoenix area is extra.
The accuracy of detector
tubes generally is considered to be +/-25% of the reading. This is based on
the criteria for certification of detector tubes as originally defined by
the National Institute for Occupational Safety and Health (NIOSH).

OSHA Employee Air
Monitoring Sampling
After reviewing the
Material Safety Data Sheets for the products used in a work area, we will
assist in determining the chemicals that should be sampled. Sampling pumps
drawing air past the sampling media are used to measure the specific amount
of chemical in the air. The air in the employees breathing zone (6” – 9”
from the mouth/nose) is drawn past the sampling media at a predetermined
Liters per minute flow rate. The contaminant is left on the sampling media
to be measured in the laboratory. The ‘up to all shift’ sampling gathers
the chemical on the sampling media so that it can be analyzed in the
laboratory. All test results from the laboratory meet the quality control
requirements of AIHA and NELAC.
The results of the samples will be compared within the
safe levels for the chemicals in OSHA’s 29 CFR 1910.1000 TABLE Z-1, Limits
for Air Contaminants. It gives you the information on your company’s levels
vs. the OSHA maximum permissible exposure limit. If your work area is over
the exposure limit we can assist with area recommendations or respirator
recommendations.
Some examples of substances we monitor for:
Acetone
Arsenic (Inorganic)
Beryllium
Cadmium
Lead
Methyl Ethyl Ketone
Silica
Zinc
The cost for air sampling for up to 5, eight hour
samples per chemical (all in one day) is approximately $2,800 with an
e-mailed air sampling report. We sample for a limited number of chemicals,
so please let us know what sampling you are interested in. Travel outside
of the Phoenix area is extra.

Noise Monitoring
Noise monitoring can be done to determine if an area
is over the OSHA limits for sound. We will sample employees and or areas
for the work shift.
The cost for noise monitoring for up to five, eight
hour noise samples (in one day) is approximately $2,800 with an e-mailed
noise monitoring report. Travel outside of Phoenix extra.
The OSHA Hearing Conservation Program
29 CFR, 1910.95(c)(1)
The employer shall administer a continuing, effective
hearing conservation program, as described in paragraphs (c) through (o) of
this section, whenever employee noise exposures equal or exceed an 8-hour
time-weighted average sound level (TWA) of 85 decibels measured on the A
scale (slow response) or, equivalently, a dose of fifty percent. For
purposes of the hearing conservation program, employee noise exposures shall
be computed in accordance with Appendix A and Table G-16a, and without
regard to any attenuation provided by the use of personal protective
equipment.
Some examples of what loud areas dBA levels sound
like:
| Threshold of Hearing |
0 dBA |
| Whisper |
30 dBA |
| Quiet Room |
45 dBA |
| Conversation |
55 dBA |
| Car Driving Nearby |
65 dBA |
| Busy Traffic Area |
75 dBA |
| Alarm Clock |
85 dBA |
| Lawnmower |
95 dBA |
| Pneumatic Drill |
105 dBA |
| Rock Concert |
115 dBA |
| Chain Saw |
125 dBA |
| Airplane at Takeoff |
140 dBA |
Respirator Two Hour Training, with
Qualitative Fit Test
If an area is determined to
require a full or half face respirator, this course plus the fit test are
required. Employees with beards or facial hair that interferes with the
respirators seal to the face can not be tested. Employees will need to be
medically qualified before the fit test. The Qualitative Fit test we use is
the ‘irritant smoke’ test to check for leaks and fit.
By using the Qualitative
Fit test with a full face respirator – the air contaminants PEL (permissible
exposure level) is raised by a protection factor of 10.
Example, if you are using
Sulfuric Acid the OSHA PEL TWA is 1 mg/m3.
Ten times 1 mg/m3 is 10 mg/m3.
With the full face respirator and correct cartridges, it would be within the
PEL to work with the Sulfuric Acid at a ‘worst case’ sampling level of less
than 10 mg/m3.
The other factor to
consider when using cartridge respirators is the IDLH level. (Immediately
Dangerous to Life and Health). The IDLH level for Sulfuric Acid is 15 mg/m3.
It is critical not to wear a cartridge respirator an area that could reach
an IDLH condition.
Respirator training
includes:
- General requirements of the
Respiratory Protection standard.
- When and where respirators are
required in your facility.
- How improper fit, usage, or
maintenance can compromise the protective effect of the respirator.
- Maintenance and storage
procedures.
- The procedure for using required
respiratory equipment
- How to use the respirator
effectively in emergency situations, including situations in which the
respirator malfunctions.
- How to inspect, put on and
remove, use, and check the seals of the respirator.
- Recognizing medical signs and
symptoms that may limit or prevent the effective use of respirators.
Pricing: $ 1,200, up to 12 attendees. Travel
outside of the Phoenix area is extra.
