Description
Ship or erection units are outfitted with propulsion equipment and support
equipment, such as plumbing, electrical installations, etc. (Also includes painting
operations after assembly, but these hazards are covered under
"painting.")
- Erection units may be outfitted before being added to the ship, or the ship may
be entirely outfitted after assembly is completed. Processes associated with outfitting
include painting, plumbing and electrical installation, installation of engines and
boilers, completion of super structure and deck equipment and rigging, etc.1
- Asbestos is used in two operations: (1)
insulating piping and exhaust manifolds; and, (2) fire-proofing (combined with other
linings) for living and working areas. Although asbestos is being replaced by magnesia
bricks, fibrous glass products and rock wool, it is still used in certain applications.2
Equipment
- All equipment associated with plumbing, electrical, and insulation installation,
carpentry, painting, boiler making, etc.
Associated Hazards
- Hearing loss from noise
- noise is pervasive. Engineering controls are difficult to implement because
workstations are not fixed. Reverberant noise and confined spaces increases hazard. An
extensive hearing protection program is required.
-
Respiratory irritation and poisoning from exposures to toxic fumes and particles during painting.
- Injuries from fire, asphyxiation, toxic exposures upon entry into confined spaces during ship building and repair.
- Eye injuries from metal chips and rust are a prevalent injury. For standards
covering eye and face protection, which requires eye protection that
meets specifications of the American Standard Safety Code for Head,
Eye and Respiratory Protection, Z2.1, see
29
CFR 1915.153.
- Fires,
explosions from welding
operations. For standards covering fire prevention during welding operations in shipbuilding and
repair, see 29
CFR 1915, Subpart D. Sections 29
CFR 1915.53(b)-(c) covers fire
prevention where welding operations involve preservative coatings. Welders sometimes use
compressed oxygen to ventilate spaces, blow dust off clothes, or cool their bodies,
thereby increasing fire hazard.3
- Exposure to pyrolysis products during welding
operations. For
standards covering welding operations in the presence of toxic preservative coatings, see 29 CFR 1915.53(d).
Hazard is increased by confined
spaces where fumes may also affect nearby workers. For standards
covering the maintenance of gas-free conditions, see 29 CFR 1915.15.
- Respiratory damage or chronic disease from exposure to asbestos - installation
of asbestos is being used much less recently. New installation methods have greatly
reduced exposure levels. Exhaust ventilation is often adequate when new application
methods are used.4 Severe exposures occur during repair when insulation is
removed. For a detailed description of a shipyard asbestos control
program, see Beckett.5
- Electrocution
from portable electric hand
tools and lights - portable tools and lights are used extensively.
Double-insulation is preferred to grounding.3
For standards covering portable hand tools, see 29 CFR 1915.132.
- Electrocution
while working on ships' electrical circuits - circuits must be de-energized and
tagged during work.3 For standards covering electrical
circuits and distribution boards, see 29 CFR 1915.181.
- Frost bite, hypothermia, heat exhaustion, heat cramps, dehydration, etc., from
exposure to extreme weather (heat stress).
- Drowning, injuries from falls - 70% of
falls result from equipment failures of scaffolds and ladders.3 For standards covering scaffolds, ladders and other
working surfaces, see 29 CFR 1915, Subpart E. Drowning results
from falls from staging, decks, and end and wings wall of dry docks. Work over and near
water requires life jackets, but compliance is difficult to enforce.3. For standards covering types and maintenance of
lifesaving equipment, see 29 CFR 1915.158.
For standardscovering personal flotation devices, which references
Coast Guard standards, 46 CFR 160 and 33 CFR 175.23, see 29 CFR 1915.158(a). OSHA has issued two instructions that concern falling hazards.
OSHA instruction STD
03-10-006 [STD 3-10.6] covers restrictions on welding from float and ship scaffolds and clarifies a
contradiction between 29 CFR 1926.451(w) and 29 CFR 1926.451(a)(18)
by allowing welding from these scaffolds providing the supporting ropes are without flaws
and of adequate size. OSHA instruction STD 1-11.2B concerns work platforms suspended from
lattice or hydraulic crane booms, and clarifies 29 CFR 1926.550(b)(2)
by allowing the use of such platforms only when the procedure is safer than alternative
available work practices.
- Thermal burns during work on ships' boilers and piping - before beginning
work, protocol for locking out the
system must be followed. For standards covering ships' boilers and
piping systems, see 29 CFR 1915.162-163.
