JOB HAZARD ANALYSIS (JHA) JHA Preparation Instructions: JHAs are to be prepared by the Supervisor or Group Manager in charge of the work, with work group member participation. The goal of preparing a JHA is for those responsible for or performing any work to review the risks and possible complications of that work and to consider ways of mitigating those risks and complications. A JHA shall be completed for all work executed. The JHA## is to be incremented when a procedure requires more than one JHA form. Standing should be marked if job or task is performed regularly and work group members are always the same individuals. Supervisors are responsible for getting the work group members sign off completed and a copy sent to the safety officer for each JHA. JHA Change Instructions: If changes to the content of this JHA are required, follow the KPNO ETS Engineering Change Process. The master copy of the document must be checked out of the Document Vault, an Engineering Change form must be completed, and the Revision Table (see last page) must be updated. Note that periodic reviews of this JHA that do not result in content changes require only entry of the review date and the name of the reviewer in the Revision Table; the document revision should not be advanced in this case.

HAZARD ANALYSIS 3500-AD-05-00-JHA Hazard Analysis Instructions: Complete the table below with the basic job steps, stating the hazards present and safe procedures or precautions to control the hazards for each step. Tab will move to next column; to add rows place cursor outside table on the right, and press ENTER. Basic Job Steps: Review the activity and divide it into basic steps. Hazards Present in Each Job Step: Identify the hazards or the possible danger present for each basic job step. Correct and Safe Procedures and Precautions: Decide what actions or procedures are necessary to control and minimize the hazards present. Things to consider: Use designations in the Hazards Present column: Do employees know how to do the job? CB Caught Between SA Struck Against What are the hazards? Include people and equipment. CBY Contacted By SB Struck By How can injuries or accidents occur? CI Caught In SL Suspended Load How can injuries or accidents be prevented? CO Caught On TH Trip Hazard Are there obvious unsafe conditions? CW Contact With Are special tools needed? E Exposure to Chemicals, Noise, Vibration, Radiation Do people need personal protective equipment? EL Electrical How would we rescue people if something went wrong? Do we have the equipment to rescue? ER Ergonomics FB Fall to Below FH Fire Hazard HS Heat stress R Repetitive Motion Item No. 2 BASIC JOB STEPS Position telescope to 39 degrees elevation and 0 degrees azimuth. Attach stay bar to Hydra and lock rotator with the key. 3 Raise crane and lift Hydra section. SL, SB 4 5 6 7 8 9 0 Lower crane and pivot X/Y stage to line up bolt holes on X/Y stage cart. Remove weights (2) from corrector lifting fixture. Lock-out/Tag-out instrument lift and return key to file cabinet. HAZARDS PRESENT IN EACH JOB STEP CBY, CW, SA, SB, SL CB, CBY, CW, SB CB, SB CBY, CW, SB CBY, CW, SB CORRECT AND SAFE PROCEDURES AND PRECAUTIONS Telescope must NOT be at zenith when using the overhead crane or it might contact the telescope. Rotator will become unbalanced during Hydra removal and could rotate on its own if not secured. Never stand or walk under a suspended load. Cart will roll. Stand on either side NOT on ends of cart. Remove weights before unbolting lifting fixture. Unbalanced fixture will swing out when unbolted. The instrument lift can NOT be used when Hydra focal plane is mounted to the side of the telescope. The lift will contact and damage the focal plane. HYDRA REMOVAL PROCEDURE Page 2 of 5
3500-AD-05-00-JHA Item No. BASIC JOB STEPS HAZARDS PRESENT IN EACH JOB STEP CORRECT AND SAFE PROCEDURES AND PRECAUTIONS 2 3 4 5 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 GUIDELINES FOR COMPLETING THE HAZARD ANALYSIS Phase of Work Environmental/Safety Hazard Precautions/Procedures A hazard is a potential danger to a Using the first two columns as a guide, person or equipment. The purpose of decide what actions or procedures are the Job Hazard Analysis is to identify ALL necessary to eliminate or minimize the hazards- both those produced by the hazards that could lead to an accident, environment and those connected with injury, or occupational illness. the job procedure. 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 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 Begin by trying to: ) engineer the hazard out; 2) provide guards, safety devices, etc.; 3) provide personal protective equipment; 4) provide job instruction training; 5) maintain good housekeeping; 6) insure good ergonomics (positioning the person in relation to the machine or other elements in such a way as to improve safety). 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 JHA should then be changed to reflect the new conditions. Finally, review your input on all three columns for accuracy and HYDRA REMOVAL PROCEDURE Page 3 of 5
