Electrical Safety Program
The Electrical Safety program is designed to prevent electrically related injuries and property damage. This program also provides for proper training of maintenance employees to ensure they have the requisite knowledge and understanding of electrical work practices and procedures. Only employees qualified in this program may conduct adjustment, repair or replacement of electrical components or equipment. Electricity has long been recognized as a serious workplace hazard, exposing employees to such dangers as electric shock, electrocution, fires and explosions.

Provide training for qualified and unqualified employees
Conduct inspections to identify electrical safety deficiencies
Guard and correct all electrical deficiencies promptly
Ensure all new electrical installations meet codes and regulations
Report electrical deficiencies immediately
Not work on electrical equipment unless authorized and trained
Properly inspect all electrical equipment prior to use
Electrical equipment shall be free from recognized hazards that are likely to cause death or serious physical harm to employees. Safety of equipment shall be determined using the following considerations:
Identification of Disconnecting Means and Circuits
Each disconnecting means for motors and appliances shall be legibly marked to indicate its purpose. Each service, feeder, and branch circuit, at its disconnecting means or overcurrent device, shall be legibly marked to indicate its purpose. These markings shall be of sufficient durability to withstand the environment involved.
A disconnecting means is a switch that is used to disconnect the conductors of a circuit from the source of electric current. Disconnect switches are important because they enable a circuit to be opened, stopping the flow of electricity, and thus can effectively protect workers and equipment.
Each disconnect switch or overcurrent device required for a service, feeder, or branch circuit must be clearly labeled to indicate the circuit's function, and the label or marking should be located at the point where the circuit originates. For example, on a panel that controls several motors or on a motor control center, each disconnect must be clearly marked to indicate the motor to which each circuit is connected. In the figure below, the Number 2 circuit breaker in the panel box supplies current only to disconnect Number 2, which in turn controls the current to motor Number 2. This current to motor Number 2 can be shut off by the Number 2 circuit breaker or the Number 2 disconnect.
All labels and markings must be durable enough to withstand weather, chemicals, heat, corrosion, or any other environment to which they may be exposed.
Definition of Terms
Qualified Worker: An employee trained and authorized to conduct electrical work.
Unqualified: Employees who have not been trained or authorized by management to conduct electrical work.
Training for Unqualified Employees
Training for Unqualified Employees is general electrical safety precautions to provide an awareness and understanding of electrical hazards..
Electrical Safety Rules for Non-Qualified Workers
1. Do not conduct any repairs to electrical equipment
2. Report all electrical deficiencies to your supervisor
3 Do not operate equipment if you suspect and electrical problem
4. Water and electricity do not mix.
5. Even low voltages can kill or injure you
6. Do not use cords or plugs if the ground prong is missing
7. Do not overload electrical receptacles
Training for Qualified Employees
Training for Qualified Employees includes specific equipment procedures and requirements of Electrical Safety, 29 CFR 1910.331 to 1910.339
Training for employees (qualified and unqualified) who face a risk of electric shock that is not reduced to a safe level by proper electrical installation. Training can be either in the classroom or on-the-job type. The degree of training required is dependent upon the risk to the employee. Specific required training includes:
Personal Protective Equipment
Employees working in areas where the potential contact with exposed electrical sources are present and likely, will be provided and shall use Personal Protective Equipment (PPE). The following rules apply to the use and care of PPEs:
1. PPEs shall be used where contact with exposed electrical sources are present and likely.
2. PPEs shall be designed for the work being performed and environment in which it is used.
3. PPEs shall be visually inspected and/or tested before use. Any defects or damage shall be replaced, repaired or discarded.
4. In cases where the insulating capabilities of the PPEs may be damaged during the work, a protective outer cover, such as leather, must be used.
5. Employees shall wear non-conductive head protection wherever there is a danger of injury from electrical burns or shock from contact with exposed energized parts.
6. Employee shall wear protective eye/face equipment whenever there is a danger from electrical arcs or flashes or from flying objects resulting from an electrical explosion.
