1 Section Five Confined Space In the fall of 1989, OSHA enacted the LOCKOUT / TAGOUT regulations because of energy-related injuries, where employees who were working on equipment became injured when another employee inadvertently turned on equipment. We can be exposed to situations calling for more often than we realize. Some of these situations are: Repairing Circuits Cleaning & Oiling Equipment Clearing Jammed Mechanisms Rebuilding Equipment Machine Setup We have an Energy Control Plan aimed at preventing employee injury with LOCKOUT / TAGOUT procedures. Typically we come into contact with different types of energy. These are: Electrical Hydraulic Pneumatic Chemical Thermal Gravity Energy of Motion 1

2 There are a number of Lock-Out devices. These include: Padlocks Chains Valve Clamps Key Blocks Pins Tagout Devices provide visual warnings. They contain information such as: Why the machine is out of service Persons servicing the machines The tags provide information only and are not a substitute for locks. We will provide identified Lockout / Tagout devices, which are durable and difficult to remove. Only certain employees are to install Lockout / Tagout devices. These are.. Electrician Toolpusher These people are authorized, and have been trained in effective Lockout / Tagout procedures for the equipment effected. For employees effected by and working around locked-out equipment, YOU WILL BE INFORMED when Lockout / Tagout procedures are in place. You are NOT ALLOWED to restart locked out machines. 2

3 If the power source is out of sight of the operating controls, use the buddy system. While one person locks out the power the Buddy observes and tests the machinery. After equipment servicing is complete proper Lockout / Tagout release procedures must be followed: Step 1: Remove all non-essential items and tools from the surrounding area Step 2: Clear personnel and make sure machine is ready to operate Step 3: All Lockout/Tagout tags and devices must be removed by the personnel who installed them. NOTE: Management can remove tags and devices, but only in emergency situations. Once Lockout / Tagout devices are removed, equipment should be test-run. This may require the buddy system. Sometimes machines must go through a temporary restart while locked out. Follow standard release procedures and then reinstall locks and tags. When working around electrical equipment additional rules must be followed. The qualified person will follow the general Lockout / Tagout procedures, but identify all sources of electricity. Then the equipment will be shut off at the point of operation before disconnecting. There are some special situations the qualified person may encounter with electrical machinery. There may be more than one energy source...locking out the main panel may be the best choice. Older or specialized machines may require fuses to be removed. 3

4 Hydraulic and Pneumatic power systems have their own characteristics and must be treated differently than Electrical. These involve pipes and valves, so there are usually hazards from pressure releases of hydraulic fluid or air. Lock out devices specifically made for these systems should be used, such as a padlock and chain or valve clamp. Our standard tag can be used. If needed bleed pressurized lines and test down stream valves. Additional precautions should be taken with major moving parts. Here we need to avoid slippage. We use blocks, pins and brackets. Isolate machines from vibrations from traffic or other machines. Shut down the machine if necessary. Lockout / Tagout is essential when working on most equipment and machines. Use COMMON SENSE and use Lockout / Tagout procedures. 4

5 When following Lockout / Tagout procedures you should: Identify all energy sources. Only qualified personnel will attach Lockout / Tagout devices. Equipment must be tested after locks/tags are in place. Qualified person removing last lockout device must make sure work is completed and equipment is safe to operate. Remember, COMMUNICATION & WORKING TOGETHER are the keys to safe Lockout /Tagout procedures. Section Five Confined Space Entries are never routine. You may use the same equipment, run the same tests, and even work with the same crews, but the conditions you face inside are very different every time, and may include low oxygen levels, gas leaks and toxic fumes. In many situations these hazards can knock you out in a heartbeat. Because of this, OSHA created the Permit-Required Space Regulations. A Confined Space is large enough for a person to enter, but access is physically limited or restricted. They are large enough to work in, but are not designed for continuous use. 5

6 Examples of confined spaces on a drilling location include: Tanks Vessels Pits Well cellars Chemical storage hoppers Trucks Some confined spaces require special safety evaluations and permits before work can be performed. Permit required confined spaces contains or could potentially contain a hazardous atmosphere, materials that could engulf the entrant, is arrange in such a way a person could become trapped or contains recognized health and safety hazards. Examples of these types of confined spaces on a drilling located include but are not limited to: Hoppers (MUD & CEMENT) Fuel / Mud / Frac / Water Tanks Cellars Sumps or Pits Without exception, NO employee should enter a confined space that is marked or unmarked, designated or known to be a Permit- Required Confined Space without checking with your supervisor to be assured all evaluations, permits and proper procedures are met and followed. NO EXCEPTIONS If you are in doubt- ASK BEFORE PROCEEDING! All personnel must always be aware of effective Confined Space permits and each Confined Space permit must be renewed with each work shift. Additional training is provided for any employee involved in a Permit (or Non-Permit) Confined Space entry. 6

7 The HOT WORK PERMIT system insures safe working conditions by defining duties and documentation requirements for hot or hazardous work. Hot work includes: Burning Welding Cutting Grinding Machines that produce sparks and the use of Electrical Devices which are NOT suitable for hazardous areas. The Supervisor in charge must complete the following before signing a HOT WORK PERMIT. Insure all safe work requirements and precautions are met. Test for explosiveness, toxicity, and potentially hazardous conditions. Insure that fire safety equipment is available and employees involved are trained in their use. Note any restrictions to the work to be performed. All personnel must always be aware of effective Hot Work permits and each Hot Work permit must be renewed with each work shift.
