In addition to the requirements and
recommendations for working in enclosed spaces, hot work is performed in
other locations, such as the exterior of the ship's hull and deck,
hollow structures, as well as locations in the shipyard such as shops,
dry docks, and tank farms.
The
following controls are required:
Note:
During shipbuilding operations, the need for testing by a shipyard competent person (SCP)
and a certified marine chemist (CMC) will depend on the progress of the vessel construction.
Until there is a potential for a hazard, such as after the introduction
of flammable liquids, testing may not be required.

Note: Confined space entry is one of the leading
hazards associated with barge cleaning. Review the
Shipbuilding: Confined/Enclosed Spaces and Other Dangerous Atmospheres
chapter for information on how to protect workers from this hazard.
Also, the module outlining the
requirements for
Hot Work in Enclosed
Spaces should be reviewed before reviewing the module regarding
Confined
Spaces, or these requirements for Other
Locations. |

Fall Hazards |
Potential Hazards:
Fall hazards are a leading cause of shipyard fatalities.
Shipyard employees are often required to work in dangerous
environments that may include fall hazards. Accidents involving
elevation equipment such as ladders and scaffolds are often serious,
even fatal. Workers also risk falls from open deck edges.
Example Solutions:
Guarding of Deck Openings and Edges
- Deck openings and edges must be guarded. [1915.73]
- Flush manholes and other small openings must be guarded after
opening. [1915.73(b)]
- During the installation of guards on large openings and deck
edges, fall protection (harness with lanyard) must be
used. [1915.73(d)]
- When floor plates or gratings (e.g. bilges, engine rooms,
pump rooms, machinery spaces) are removed, the openings must be guarded or planked. [1915.73(f)]
Fall Protection for Scaffold Work
- Guardrails or other appropriate fall protection must be
used when working on scaffolds 5 feet above solid surfaces. [1915.71(j)]
- During the installation of guards on scaffolds, fall
protection must be used. [1915.73(d)]

Maritime Labor/Industry Recommendations
|
- Maritime Labor/Industry recommends that personal fall protection including
lanyards and harnesses be used and secured during installation
of guardrails.

PPE Requirements |
Potential Hazards:
In most cases, respiratory protection requirements are less
restrictive in locations other than confined/enclosed spaces,
due to the natural ventilation available. However, numerous
workers may be performing other work nearby and may be at risk
of exposure to:
- Toxic metal fumes, vapors, and gases from welding.
- Ultraviolet radiation from arc welding.
- "Spatter" from hot metal.
- Fire and explosion from nearby operations using flammable
or combustible materials.
Requirements and Example Solutions:
- Provide shielding for welding when practical. If not
practical, UV filter lenses must be worn by employee at
risk. [1915.56(e)
and 1915.51(e)(1)(ii)]
- Do not allow use of chlorinated solvents within 200
feet of the exposed arc of welder. [1915.51(e)(1)(i)]
- Use appropriate PPE for welders and helpers.
[1915.51(e)(1)(ii)]
- Use airline respirators when welding on beryllium
containing base or filler metals. [1915.51(d)(3)]
