Study Notes

Mishap Severity Categories

Category I - Catastrophic mission capability or unit readiness.
- Permanent partial disability or severe injury or illness.
- Extensive damage to equipment or systems.
- Significant damage to property or the environment.
- Security failure.
- Significant collateral damage
Category II - Critical mission capability or unit readiness.
- Significant injury or illness.
- Extensive damage to equipment or systems or property.
- Environmental damage.
- Significant operational impact.
Category III - Degraded mission capability or unit readiness.
- Minor damage to equipment, systems, property, or the environment.
- Minor injury or illness.
Category IV - Little or no adverse impact on mission capability or unit readiness.
- Minimal threat to personnel, safety, or health.
- Slight equipment or systems damage, but fully functional and serviceable.
- Little or no property or environmental damage.

Mishap Probability Codes

Subcategory A - Likely to occur, immediately or within a short period of time.
- Expected to occur frequently to an individual item or person; or continuously over a service life for an inventory of items or group.
Subcategory B - Probably will occur in time.
- Expected to occur several times to an individual item or person; or frequently over a service life for an inventory of items or group.
Subcategory C - May occur in time.
- Can reasonably be expected to occur sometime to an individual item or person; or several times over a service life for an inventory of items or group.
Subcategory D - Unlikely to occur, but not impossible.

Hazard Severity and Mishap Probability

Hazard Severity: Determines the severity based either on the Naval Asbestos Facility Score (NAFS) if available in the activity's asbestos inventory or from a judgment of the condition of the asbestos involved.
Probability: Determines the number of people exposed to asbestos then the number of hours per week the average person is exposed.

Mishap Classifications

Class A - The resulting total cost of damages to DoD or non-DoD property in an amount of $2 million or more; a DoD aircraft is destroyed; or an injury and/or occupational illness result in a fatality or permanent total disability.
Class B - The resulting total cost of damages to DoD or non-DoD property is 500,000ormore,butlessthan500,000 or more, but less than 500,000ormore,butlessthan2 million. An injury and/or occupational illness result in permanent partial disability or when three or more personnel are hospitalized for inpatient care (beyond observation) as a result of a single mishap.
Class C - The resulting total cost of damages to DoD or non-DoD property is 50,000ormore,butlessthan50,000 or more, but less than 50,000ormore,butlessthan500,000; or an event involving one or more DoD personnel that results in one or more days away from work.

Globally Harmonized System (GHS) Label Elements

Symbols (hazard pictograms): Convey health, physical and environmental hazard information, assigned to a GHS hazard class and category.
Signal Words: "Danger" or "Warning" are used to emphasize hazards and indicate the relative level of severity of the hazard, assigned to a GHS hazard class and category.

Hierarchy of Preferred Control Measures for Fall Hazards

Elimination: Removing the hazard from a workplace. This is the most effective control measure.

Mishap Reporting

Safety departments document all mishap notification and support received.
Mishap investigators complete written reports with factual findings, root causes, and corrective actions for prevention.
For civilian personnel mishaps, the investigator releases factual information to the ICPA but is forbidden to release privileged safety information, such as analysis, findings, and recommendations.
Safety departments forward recommendations to relevant department heads and supervisors, follow up on progress, and notify command personnel.
All mishaps meeting reporting criteria are reported electronically to COMNAVSAFECEN using the Web-Enabled Safety System (WESS) or other appropriate format from reference 14-2.
Guidance on mishap information, privileged safety information, and the conduct of Safety Investigation Boards is provided in reference 14-2.

Fall Hazard Control Measures

Elimination: Removing the hazard from the workplace is the most effective control measure.
Delaying the task: If no time deadline exists, consider delaying the task to allow for risk elimination or development of new controls over time.
Transfer of Risk: Shifting the mission or task to a more suitable unit or individual that can mitigate the risk.
Compensation: Assigning redundant capabilities to compensate for potential losses.
Determine Control Effects: The control's effect on severity and probability should be re-assessed, determining the residual risk.
Cost Consideration: The cost of implementing controls and potential interactions between controls should be considered.
Risk Decision: Determining if the residual risk is acceptable, balancing the risk against the mission's potential benefit and value.
Implementing Controls: Following risk control decisions, implementation is the next step.

Mishap Categories

Category I: Mission failure or loss of life.
Category II: Permanent partial disability, severe injury or illness, significant equipment or system damage, property or environmental damage, security failure, or significant collateral damage.
Category III: Degraded mission capability or unit readiness, minor equipment damage (fully functional), minor injury or illness, or minor property or environmental damage.
Category IV: Minimal impact on mission capability or unit readiness, minimal threat to personnel safety or health, slight equipment damage (fully functional), or minimal property or environmental damage.

Mishap Probability Codes

Subcategory A: Likely to occur immediately or within a short period of time, occurring frequently to an individual item or person, or continuously over the service life for an inventory.
Subcategory B: Probably will occur in time, occurring several times to an individual item or person, or frequently over a service life for an inventory.
Subcategory C: May occur in time, occurring some time to an individual item or person, or several times over a service life for an inventory.
Subcategory D: Unlikely to occur, but not impossible.

Hazard Severity & Mishap Probability

Hazard Severity: Defines severity based on the naval asbestos facility score (NAFS) or a judgment of the condition of the asbestos.
Probability: Determined based on the number of people exposed to asbestos and the number of hours per week the average person is exposed.

Personal Protective Equipment (PPE)

The best way to protect personnel is to eliminate the hazard.
Engineering controls are the preferred method for minimizing hazard exposure.
A PPE program should be implemented when engineering controls are not feasible.
Activities provide PPE when deemed necessary to reduce occupational injuries or illnesses.
PPE procurement and enforcement of proper use and maintenance are the responsibility of the activity.
PPE offers a last line of defense and does not eliminate the hazard.
Misapplication or improper maintenance can render PPE ineffective, highlighting the importance of equipment selection, maintenance, training, and enforcement of proper use.

Safety Councils and Committees

Safety Councils and Committees: Formed to discuss safety issues, generate recommendations, monitor safety programs, and promote safe practices.
Membership: Members include supervisors, employees, and safety professionals, representing different levels of the activity and various areas of expertise.
Functions: Identify hazards, develop safety procedures, conduct safety inspections, investigate accidents, and evaluate safety programs.
Safety Training: Safety officers, managers, and hygienists require continuing education and training, including annual CEU requirements.

Training and Continuing Education

Formal classroom training is not mandatory, but documentation is required for any meetings or informal training.
Non-industrial areas utilize monthly or periodic meetings to distribute safety information.
Safety professionals require continuing education for certification and knowledge retention.
CEU requirements vary based on profession and level of experience.
The hours and CEUs required are a minimum, and knowledge and understanding of the subject matter are the ultimate measures of success.
