NWR is committed to providing employees and others a safe and healthy working environment on projects. We have developed and promoted a safety program, designed to prevent accidents. The NWR Safety Manual outlines policies and procedures to prevent injuries, illnesses, and loss to property and to the environment during all phases of the project.

The Safety Program for National Waterproofing & Restoration has been developed to govern activities for all personnel employed in any capacity of NWR. The Safety Program Manual is dedicated to the goals as stated in the Occupational Safety and Health Act of the United States of America and was adapted to the Qatari Standards. The main objective of the regulations is to provide a work place, free from recognized hazards.

Accidental loss can be controlled through proper management in combination with active employee participation. Loss prevention is the direct responsibility of all managers, supervisors and employees. All employees must perform their jobs properly and professionally at all times. Personal commitment to safety must be viewed as a way of life.

Safety practices in place allowed us to perform large projects such as HIA with over 15,000,000 million hours accident free.
