HAZARD ANALYSIS

 

Step

Description of Step

Safety Hazards/

Potential Impacts to Environment

Mitigations / Precautions / Safety Procedures / Controls

1

Prepare to relieve cold head pressure

 

Miscommunication

 

 

Inappropriate equipment

 

Inadvertent exposure to high pressure gases

 

 

 

Communicate steps to those performing work

 

Use only approved fixturing

 

 

Rope off area and post signs to keep casual   bystanders stay out of work area.

 

 

2

 

Remove supply and return lines of the cold-head and install Aeroquip device to relief the 200psi pressure safely (with low flow 5-20slm with reduced ODH) on the supply line to atmosphere

 

 

 

Pressure hazard

 

All workers must have pressure training

Wear safety glasses and hearing protection

Ensure fixture openings are pointed away from personnel

Slow relief with appropriate Aeroquip fitting

3

 

Once it is in atmosphere, then opening the coldhead to the free piston mechanism

 

 

No hazard

 

N/A

4

 

Reassembling the coldhead and then repressurizing to initial pressure

 

 

 

No hazard during reassembling, but there is a pressure hazard when pressurizing

 

 

Appropriate Aeroquip fitting will be used with a regulator to pressurize gently back to original pressure on the supply end.

5

 

N/A

 

 

ODH area

 

ODH training, oxygen monitors are required because the cold-heads are in the ODH-1 area.

GUIDELINES FOR COMPLETING THE HAZARD ANALYSIS

 

Phase of Work

Safety Hazards/Potential Environmental Impacts

Mitigations / Precautions/Procedures/Controls

Examining a specific job by breaking it down into a series of steps or tasks, will enable you to discover potential hazards employees may encounter.

 

Each job or operation will consist of a set of steps or tasks. For example, the job might be to move a box from a conveyor in the receiving area to a shelf in the storage area. To determine where a step begins or ends, look for a change of activity, change in direction or movement.

 

Picking up the box from the conveyor and placing it on a hand truck is one step. The next step might be to push the loaded hand truck to the storage area (a change in activity. Moving the boxes from the truck and placing them on the shelf is another step. The final step might be returning the hand truck to the receiving area.

 

Be sure to list all steps needed to perform the job. Some steps may not be performed each time; an example could be checking the casters on the hand truck. However, if that step is generally part of the job it should be listed.

 

Close observation and knowledge of the job is important. Examine each step carefully to find and identify hazards- the actions, conditions, and possibilities that could lead to an accident. Compiling an accurate and complete list of potential hazards will allow you to develop the recommended safe job procedures needed to prevent accidents.  

A safety hazard is a potential danger to a person or equipment. An environmental impact is a change to the environment.   The purpose of the Hazard Analysis (HA) is to identify ALL hazards- including those produced by the environment, those connected with the job procedure, and those with the potential to result in an environmental impact.

 

To identify hazards, ask yourself these questions about each step:

 

Is there a danger of the employee striking against, being struck by, or otherwise making injurious contact with an object?

 

Can the employee be caught in, by, or between objects?

 

Is there potential for slipping, tripping, or falling?

 

Could the employee suffer strains from pushing, pulling, lifting, bending, or twisting?

 

Is the work environment hazardous to safety and/or health (toxic gas, vapor, mist, fumes, dust, heat, or radiation)?

 

Are there electrocution hazards?

 

Will action require soil/erosion control?

 

Will chemicals or petroleum products be used in an area where they could be released into the environment?

 

Will action have the potential to affect storm water (drains, ponds, or streams in the vicinity)?

 

Will action have the potential to affect the sanitary water system?

 

Will action involve refrigerants?

 

Will any regulated or recyclable waste be generated?

Using the first two columns as a guide, decide what actions or procedures are necessary to eliminate or minimize the hazards that could lead to an accident, injury, or occupational illness.

 

Consider the hierarchy of controls:

(1)    Elimination (physically remove the hazard)

(2)    Substitution (replace with something less hazardous)

(3)    Engineering controls (isolate the hazard)

(4)    Administrative controls (change the work)

(5)    Applicable / Specific PPE

 

List the recommended safe operating procedures. Begin with an action word. Say exactly what needs to be done to correct the hazard, such as, “lift using your leg muscles.” Avoid general statements such as, “be careful”, “use caution”, and “be alert”.

 

List the required or recommended personal protective equipment necessary to perform each step of the job.

 

Give a recommended action or procedure for each hazard.

 

Serious hazards should be corrected immediately. The HA should then be changed to reflect the new conditions.

 

Finally, review your input on all three columns for accuracy and completeness. Determine if the recommended actions or procedures have been put in place. Re-evaluate the job safety analysis as necessary.


I have reviewed this hazard analysis and I understand the hazards and required precautionary actions.   I will follow the requirements of this hazard analysis or notify my supervisor or Fermilab contact if I am unable to do so.
