Compartment Name/Number/Type/Equipment(s):
MMR #1/Machinery Spaces/Inclined Stairs

Issue(s)/Hazard(s) Description:
Incorrect stair handrail design:
1. Last stanchion for handrail should be vertical, not perpendicular with stringer.
2. There should be a two-tiered handrail on an exposed side of stairs.

Potential Mishap (Risk):
Risk of injury to personnel (slip, fall).

Reference Criteria:
•    ASTM F1166 – 2007, Section 11.8
•    ABS Guide for Crew Habitability on Ships, Appendix 3, Page 82, Item 30.

Compartment Name/Number/Type/Equipment(s):
Passageway (1-41-02-L)/Passageway/Inclined Ladder

Issue(s)/Hazard(s) Description:
Inadequate overhead vertical clearance for 95th percentile male. Inclined stair is 60° from horizontal and provides
76" of clearance from tread to pipe. This could be adequate when ascending, but when descending, the upper
torso is leaning forward and is more susceptible to contacting the pipe.

Potential Mishap (Risk):
Risk of injury to personnel (head-knocker).

Reference Criteria:
•   ASTM F1166 – 2007, Section 11.2.3.
•   ABS Guidance Notes for the Application of Ergonomics to Marine Systems, Section 9, pars. 2.1 and 3.2.

Recommendation(s):
1. Increase the overhead clearance to at least 80” (84” preferred).
2. Decrease the angle of inclination of the stairs to less than 60° (inclined stairs not recommended).




                                                                                                      Page 7 of 25

Compartment Name/Number/Type/Equipment(s):
Access/4-47-4-L/Passageway/Inclined Ladder

Issue(s)/Hazard(s) Description:
The tread depth is 4 1/2" which provides inadequate stepping surface, especially when descending. Personnel
face away from the treads when descending which causes only part of the step to be utilized (approx. 3 1/2").
Additionally, the back of the leg hits the step above and keeps the heel from completely landing on the tread.

Potential Mishap (Risk):
Risk of injury to personnel (slip, fall).

Reference Criteria:
•    ASTM F1166 – 2007, Section 11.2.3.
•    ABS Guidance Notes for the Application of Ergonomics to Marine Systems, Section 9.3.2.

Recommendation(s):
Increase the depth of the tread to, at a minimum 9", preferably 10.9" IAW ASTM F1166 – 2007 and the ABS Ergo
Guide.




                                                                                                    Page 8 of 25

Compartment Name/Number/Type/Equipment(s):
Stair Tower (4-72-6-7)/Passageway/Inclined Stairs

Issue(s)/Hazard(s) Description:
Ladder accesses the weather deck and is a frequently used material handling route. As a result, personnel
descending ladder carrying materials often do so without using the handrails. In addition, the stair angle is inclined
63° from horizontal. Inclined ladders should not be used in areas of high material handling; one hand must always
be free to grasp the railing.

Potential Mishap (Risk):
Risk of injury to personnel (slip, fall).

Reference Criteria:
•     ASTM F1166 – 2007, Section 11.1.3.
•     ABS Guide for Crew Habitability on Ships, Appendix 3, Page 83, Item 34.

Recommendation(s):
1. Inclined stairs are not recommended IAW ASTM F1166 – 2007. These stairs promote unsafe translation as
   depicted here descending facing outward using no hands for stability especially when the angle exceeds 60°
   which this does and is unacceptable. Mishaps are inevitable and recommend replacing with stairs less than
   50° or vertical ladders for a reduction in trips and falls.
2. Procedure should dictate that personnel should translate inclined stairs backwards (facing steps) and should
   never carry materials that require both hands.




                                                                                                        Page 9 of 25

Compartment Name/Number/Type/Equipment(s):
Stair Tower/Passageway/Stair Handrails

Issue(s)/Hazard(s) Description:
Handrails should be at least 1.5” circular pipe and should have non-slip surfaces. This crew-modified handrail
wrapped in line actually adds grip to the surface for improved safety.

Potential Mishap (Risk):
Risk of injury to personnel (slip, fall).

Reference Criteria:
•    ASTM F1166 – 2007, Section 11.2.11
•    ABS Guide for Crew Habitability on Ships, Appendix 3, Page 83, Item 30.

Recommendation(s):
Handrails should be designed IAW ASTM F1166 – 2007 and the ABS Hab Guide. Crew modifications such as this
are indications that non-slip may be required for this location.




                                                                                                   Page 10 of 25
