Safety
The objectives of the Safety Section are to:
- Explain Energy Control & Reliability and its use.
- Describe the location and utility of all safety features.
- Provide general guidelines for personal, mechanical, and electrical safety.
- Illustrate the locations of safety features for each station.
- Isolate the identified potential hazardous energy sources, including stored energy.
- A qualified person shall use test equipment to test electrical circuit elements and parts of the equipment to which there will be employee exposure and shall verify that circuit elements and equipment parts are de-energized.
Everyone is responsible for his or her own safety. After assuring that no personnel are exposed, and successfully disconnecting the energy source, the push buttons, or normal operating controls will be manipulated to make certain
Always ensure:
- The equipment or process is clear of tools and materials.
- After servicing and / or maintenance is completed and the equipment can be returned to normal production operation, determine that no personnel in the area are exposed, remove all personal tools from the equipment and return them to the proper place. Notify affected employees that the equipment is about to be restarted. Operate the isolated energy devices to restore energy, and then cycle the equipment to ensure proper operation.
Exclusive control is defined as providing the employee conducting the assigned task with exclusive control for startup of the equipment.
It is most applicable under the following conditions:
- The assigned task requires the machine or equipment to be energized for troubleshooting, testing, positioning, and other purposes.
- The assigned task is routine, repetitive, and integral to the normal production operation and it does not require the dismantling or replacement of major machine or equipment components.
Devices utilized for exclusive control are:
- Circuit control devices, such as emergency stop and start controls, providing they render the equipment inoperative and are secured by the employee, thus preventing operation without his/her knowledge and consent
Safety Overview
EXPLANATION OF NOTICES
Danger, Caution, and Warning notations are used throughout this manual to alert the reader to safety concerns which, if procedures are not properly performed, could cause death, serious injury, or equipment damage. The boxed Danger, Caution, and Warning notations will always appear before the information or step to which they pertain. These notations are listed below in ascending order of importance. Safety instructions in this operating manual are marked as follows:
Due to variations found in the operating conditions of certain applications and their working environments, the special notations in this manual cannot identify all potential problems or hazards. Caution and discretion must always be used while operating machinery, especially when using electrical power. Equipment should be operated and maintained only by trained personnel.
GENERAL SAFETY GUIDELINES
Other company, industry, and / or government mandated safety guidelines may also apply.
The following general safety guidelines are an overview of the safety topics covered in this section. While these guidelines provide information that will help prevent personnel injury and damage to equipment, read the entire section in this manual as well as the safety sections in the OEM documentation provided with this manual for a thorough understanding of safety practices and specific devices related to the equipment.
Read this entire manual and become thoroughly familiar with the machine operation and safety features before working on any part of the system.
Follow all System Operating Safety precautions outlined in this manual The following guidelines must be followed in order to promote the safety of the operation and maintenance personnel:
- Adopt good work habits regarding safety when working on or around the system.
- Maintain clean and safe work areas at all times.
- Read and obey all signs posted on and around the system.
- Do not remove or tamper with any safety guards, or other safety equipment built into the system. Operators must not try to defeat any safety feature. Doing so could result in severe personal injury.
- Always dress properly for the job and use appropriate sight and hearing protection. Personal Protective Equipment (PPE) approved safety glasses must be worn by anyone working near the line. When required, personnel must wear protective work gloves to protect themselves from cuts or lacerations that can result from the sharp edges of metal parts used in this process. Do not wear gloves near moving parts. Ear protection and hard hats may also be required where applicable based on plant dictates.
- When equipment is shut down by proximity limit switches, Emergency Stop pushbuttons, or other safety devices; no person should begin maintenance repairs until the shutdown procedures are completed, using the proper Personal Protective Equipment (PPE) where applicable
- Become thoroughly familiar with the location and function of all safety devices on the system.
Understand the system's stack light color coding.- Follow all Electrical and Mechanical System safety precautions outlined in this manual and dictated by plant safety specifications.
- Use tools properly and safely whenever working on the system
