materials (HAZMAT) training on materials present (or potentially present) as required by OSHA, the
customer, and other regulatory agencies.
Considerations for Protecting Personnel
Always evaluate the site environment as though your life depends on it. Make sure that you
understand the physical nature of the location where you will be working. Table 2-1 provides a
general guideline for evaluating an installation site.
Table 2-1: Considerations for Protecting Personnel
Indoor or outdoor: dress appropriately
If outdoor, what kind of environment, terrain, etc. Watch out for local insects and rodents
(bees, spiders, snakes, etc.)
If indoor or outdoor: determine if there are any pieces of dangerous equipment or any
processes which might be a risk to your safety
If in a tunnel, bunker, etc. watch out for a build-up of toxic or flammable gases. Make sure
the air is good. Watch out for local insects and rodents (bees, spiders, snakes, etc.)
Hazardous or Non-Hazardous Environment: wear appropriate safety equipment and
perform all necessary safety measures.
Before installing any equipment or power or ground wiring, make sure that there are no
lethal (life-threatening) voltages between the site where the instrument is to be installed
and other equipment (such as pipes or cabinets) or to earth itself.
Never assume that adjacent or peripheral equipment has been properly installed and
grounded. Determine if this equipment and the RTU or flow computer can be touched
simultaneously without hazard to personnel and/or equipment?
Be prepared. Before going to remote locations where there are few or no human
inhabitants ask a few simple questions like, should I bring water, food, hygienic materials,
first aid kit, etc?
Observe the work habits of those around you – for your own safety!
Some of the items that a service person should consider before ever going onsite can be
determined by simply asking questions of the appropriate individual. Obviously other safety
considerations can only be established at the installation site.
Considerations for Protecting Equipment
Always carefully evaluate the site installation/service environment and equipment. Understand the
various physical interfaces you will be dealing with such as equipment mounting and supporting,
RTU/flow computer analog and digital circuits, power circuits, communication circuits and various
electrical grounds. Table 2-2 provides a general guideline for evaluating the equipment protection
requirements of an installation site.
