Portable Refrigerated Sampler
Appendix C General Safety Procedures
The safety of the personnel who use the BLZZRD sampler is a
critical consideration. The following procedures, applicable to
working in and around manholes and sewers, are those used by
Black & Veatch, a respected consulting firm, and are published
here by their permission.
Field personnel must keep safety uppermost in their minds at all
times. When working above ground, rules of common sense and
safety prevail. However, when entering manholes, strict safety
procedures must be observed. Failure to do so could jeopardize
not only your own life, but also the lives of other crew members.
WARNING
The BLZZRD has not been approved for use in hazardous
locations as defined by the National Electrical Code.
CAUTION
Before you install any sampler, you must take the proper safety
precautions. The following discussion of safety procedures
offers only general guidelines. Each situation in which you
install a sampler varies. You must take into account the individ-
ual circumstances of each installation.
Additional safety considerations, other than those discussed
here, may be required. Check applicable guidelines, codes, and
regulations of federal, state, city, and county agencies.
C.1 Hazards
There are many hazards connected with entering manholes.
Some of the most common hazards are:
•
Adverse Atmosphere
–
The manhole may contain
flammable or poisonous gases or the atmosphere may be
deficient in oxygen. Forced ventilation may be necessary.
•
Deteriorated Rungs
–
Manhole steps may be corroded
and not strong enough to support a man. It may be
difficult to inspect the rungs because of poor lighting.
•
Traffic
–
Whenever manholes are located in the traveled
way, barricades and warning devices are essential to
direct traffic away from an open manhole.
•
Falling Objects
–
Items placed near the manhole opening
may fall and injure a worker in the manhole. All loose
items should be kept away from the manhole opening.
