Chapter 6
-Safety and Hazardous Materials-

This chapter covers safety rules and regulations, DCPO and MOPP Levels.

• As a petty officer you are responsible for ensuring the safety awareness of others.

• Safety: The ultimate responsibility for the safety of the command lies with the commanding officer.

Division Safety Petty Officer reports directly to the division safety officer in all matters concerning their division. Division Safety Petty Officers are responsible for mishap prevention, training and maintaining records in the division.

• The objectives of a safety program is to improve operational readiness.

• Safety Council: some large commands may have a safety council. They meet once a month.

• Master-at Arms/Safety Force is a vital link in the unit safety organization. They can act as roving inspectors for hazardous conditions.

• Equipment Tag-Out procedures: If you are not familiar with the Navy Tag-out system, please review pages 6-5 and 6-6.

OPNAVINST 3120.32 contains basic guidelines for tag-out procedures.

• The equipment tag-out bill has three purposes:
1. Provides a procedure for personnel to prevent the improper operation of a component, system, equipment, etc.
2. To provide a procedure for personnel to use when operating an instrument that is unreliable.
3. To provide procedures for personnel to accomplish maintenance (PMS).

• Tag Out logs control the entire tag out procedure. The size of the ship will determine the number of tag-out logs. The individual force commanders specify the number of logs.

• The tag-out log is a record of authorization of each effective tag-out action. It contains the following documents:
- A copy of the main instruction of any current directives (kept in front of the log)
- A Danger/Caution tag-out index and record of audits
- Cleared Danger/Caution tag-out records

• Audits are an important part of the tag-out system. They can detect discrepancies quickly and effectively. Audits are required at least every 2 weeks for conventional ships. Nuclear powered ships require weekly audits.

• Hazardous Materials Information System (MSDS) Material Safety Data Sheets provide information on hazardous materials to people that work with these materials.

• For information on cleaning solvents refer to NSTM Chapter 631

• Cleaning Solvent Precautions: As a petty officer you are responsible to use the following safety precautions:
- Proper ventilation
- Wear protective clothing, goggles, respirators, gloves, etc.
- Ensure accessible fire-fighting equipment is nearby.

• Ventilation for enclosed spaces is an air exchange every 3 minutes

• Chemical, Biological, and Radiological Defense (CBR):
This will cover the four MOPP levels. MOPP stands for Mission Oriented Protective Posture.

• The higher the level, the greater the threat, and the more your readiness level increases.

• MOPP Level – 1: Suspected. Issue protective equipment, set yoke/condition III wartime steaming.

• MOPP Level – 2: Possible. Maintain mask in carrier on your person. Test counte-rmeasures, wash down system.

• MOPP Level – 3: Probable. Don chemical protective suit, hood down. Go to GQ, set material condition Zebra.

• MOPP Level – 4: Imminent. Don protective mask, hood up, active counter-measures wash down system, set circle William (ventilation).

• You can promote safety by using safety inspections, posters, safety patrols, and warning & caution signs.

• Damage Control Petty Officers are assigned to maintain damage control equipment and closures in the divisional spaces. DCPO must complete their PQS before being designated as a DCPO. They normally serve as a DCPO for 6 months.

• Damage Control Closure Log Entries are maintained at all times, in port or underway (24-7). This log will show if any existing material condition of readiness has been modified. The maximum time any closure or fitting can be logged open is 24 hours.

• Review Chapter 6 MR for 3&2.
