devices seem to be just about everywhere. Moreover, with their large
numbers and frequent use, it is not surprising that hoisting devices play
a large role in on-the-job injuries.
Wastewater personnel handle materials on a daily basis. Sometimes
these materials need to be moved from one location to another. One-ton
chlorine cylinders, for example, must be changed out and moved to keep
the plant disinfection process in operation. Obviously, moving 1-ton cyl-
inders of chlorine or other chemical would not be possible without using
some type of hoisting apparatus.
The hoisting devices that seem to require the most attention are
chains, slings, and ropes. Chains, slings, and ropes are commonly
used between cranes and hoists and the load so the load may be lifted
and moved to the desired location. When workers use chains, slings,
and ropes in the hoisting process, they must ensure that they visually
inspect each device before use and during operation. Damaged or defec-
tive chains, slings, and ropes must be removed from service.
1.13.15 bloodborne Pathogens (29 Cfr 1910.1030)
Although scientific research has determined (at present) that HIV
and other bloodborne pathogens are not found in the wastewater stream
(except in strictly controlled laboratory conditions), the Centers for
Disease Control (CDC) does warn that persons who provide emergency
first aid could become contaminated. Thus, if your facility requires
employees trained in first aid to render medical assistance as part of
their job activities, your facility is covered under this standard. The
major point to get across to all workers is that, if they render any kind of
first aid assistance whereby the rescuer could be exposed to another per-
son's body fluids, then care and caution must be exercised. It is a good
idea to equip all wastewater facilities with first aid kits that are designed
to protect against bloodborne pathogens. These kits are equipped with
the following:
1. Rescue barrier mask to prevent mouth-to-mouth contact
2. Alcohol cleansing wipes for cleanup
3. Latex gloves to prevent hand contact with body fluids
4. Safety goggles to prevent body fluids from entering eyes
5. Biohazard bag for disposal of cleanup materials
Training should be provided to each worker on the dangers of blood-
borne pathogens. Careful attention to personal hygiene habits should
be stressed. Workers should be informed that handwashing is one of
their best defenses against spreading infection, including HIV. Ensuring
worker awareness is the key to complying with this standard.

that are required by OSHA and other regulators to be used in industry
and at wastewater treatment facilities. There are several other safety
