Perhaps the most critical safety protocol when repairing a drill press at your manufacturing facility is your LOCKOUT TAGOUT program.
What is a LOCKOUT TAGOUT Program?
This program identifies specific locking/tagging equipment and establishes specific procedures for de-energizing and discharging stored energy so that work can safely be conducted on machinery and equipment. The lockout tagout (“LOTO”) program assures that all energized and moving parts of the equipment are isolated and cannot be operated during LOTO status.
A strong LOTO program entails:
- A central location for all lockout tagout equipment;
- Standard equipment, consistent in color, shape, size, font, and format so as to be easily identifiable by all employees;
- Standard equipment which is durable and proven to withstand all environmental conditions (rain, snow, ice, heat, cold) in which it may be used;
- Sturdy equipment which affixes securely to the equipment which is being locked out, and which cannot be removed or have its seal broken inadvertently;
- A documentation system which clearly identifies the person affixing the LOTO device, and identifying the purpose of the LOTO status;
- A unique key or combination for each device, so that one key will not open multiple locks.
When used for electrical work, LOTO must occur at the circuit disconnect switch.
- When and how to use the LOTO procedure
- Specific steps for shutting down equipment, isolating power sources, discharging stored energy, and securing equipment
- Proper placement and removal of LOTO devices
- Testing of machinery or equipment prior to commencement of work
Drill Press Repair: LOCKOUT TAGOUT Protocol
Using our example of repairing an industrial drill press, the following steps must be followed:
- Notify all affected employees of equipment lockout/tagout
- Shut down the machine
- Isolate and/or block the energy source
- Lockout/tagout the energy source(s) by affixing the lockout or tagout device
- Discharge stored energy
- Verify equipment isolation from energized sources
Prior to removing LOTO devices and restoring power to the drill press, the following steps must be followed:
- Remove tools and materials from the work site
- Advise coworkers that LOTO devices are being removed
- Clear non-essential employees from the work area
- Verify power controls are in “OFF” position
- Remove LOTO devices
- Re-energize equipment
- Conduct test to verify working condition
Authorized and affected employees – those exposed to hazardous energy – must be trained in LOTO. OSHA 3120 lockout tagout regulations can be found here. There is no substitute for safety, and nowhere is that more evident than in the manufacturing industry. What does your lockout/tagout policy look like?
