Electrical, Control & Instrumentation Safety

INTRODUCTION

This training course emphasises the importance of arc flash electrical safety with reference to shock hazards, burns, incident energies, limits of approach, personal protective equipment, and arc flash mitigations.

An arc flash may happen when conductive objects are placed near exposed conductors. Dropped tools may also cause sparks that may lead to arc blasts. Arc flash safety measures also mention the importance of inspecting old electrical tools with bad parts or worn-out wires. It is very harmful because of the intense degrees of temperature it produces. When the electrical current jumps, it may also cause extremely bright flashes of light that can temporarily or permanently damage eyesight.

Employers of electrical workers are already required to conduct arc flash analysis in order to check how much thermal energy can be produced within the workplace. The results of their analysis will determine the particular amount of heat-resistant clothing that they should provide their workers. It also sets the boundaries between workers and potential sources of harmful arc flashes.

Participants attending the ELECTRICAL SAFETY: Importance of Electrical Safety, Identifying Risks and Hazards, Catastrophic Effects of Arc Flash training course will develop the following competencies:

• Understand the causes of arc flash and its effects.

• Comprehend the OSHA and NFPA 70 arc flash boundaries and limits of approach.

• Appreciate the merits incident energy calculations.

• Inculcate the safety requirements and cultures.

TRAINING OBJECTIVES

This training course aims to enable participants to achieve the following objectives:

• Understand the importance of safety in an electrical installation.

• Comprehend the hazards of arc flashes.

• Ability to accept the importance of arc flash studies.

• Appreciate the effects of incident energy.

• Assess the importance of electrical safety.

WHO SHOULD ATTEND?

This training course is designed specifically for those professionals at all levels of personnel in an electrical installation. It will enable them to understand the importance of electrical safety, identify the causes and hazards of arc flash.

This course is suitable for a wide range of technical professionals but will greatly benefit:

• Electricians.

• Electrical supervisors.

• Plant electricians.

• Operations & maintenance engineers, supervisors & technicians.

• Maintenance technicians.

It is also a useful introduction for inexperienced Electrical and I&C engineers (i.e., graduates and the like) to gain an understanding of the practical issues that they will face in their careers.

TRAINING APPROACH

This training course will combine presentations with interactive practical exercises, supported by video materials, activities, and case studies. Delegates will be encouraged to participate actively in relating the principles of stress management to the particular needs of their workplace.

There will be adequate time given for group discussion during and at the end of each session, including detailed case studies and anecdotes based on the subject matter and the facilitator’s own experience in the field.
