Commitment to Health and Safety
HGL is committed to providing safe and healthful working conditions for its employees, as well as protecting its subcontractors, the communities in which it works, and the environment. HGL promotes sound safety practices based on the identification and control of occupational health and safety (H&S) risks where its employees work. HGL does this by effective project and task planning; by staffing its projects with knowledgeable and skilled professionals; by carefully selecting its subcontractors and business partners; by executing projects per approved plans; by monitoring performance; and by reviewing and updating H&S programs and procedures annually and when new potential risks are identified. As an organization, HGL is dedicated to the following:
- Protecting the H&S of its employees through anticipation, recognition, and control of hazards in the workplace by assessing the hazards of each new task, identifying effective hazard controls, documenting the hazard controls, training personnel on hazard controls, and monitoring work to verify that hazard controls are implemented and are effective;
- Complying with applicable H&S regulations and client requirements wherever work is performed;
- Ensuring that employee H&S is an integral aspect of HGL’s culture and services;
- Enabling and encouraging all personnel to report incidents and potentially unsafe conditions and to stop work, as needed, to prevent accidents;
- Investigating incidents, identifying effective improvements, and tracking completion of improvement actions to minimize the probability of future incidents; and
- Conducting monthly and annual senior management level reviews of the effectiveness of HGL’s H&S programs and procedures and striving for continual improvement.
Health and Safety Performance
Since its incorporation in 1987, HGL has not received an OSHA citation or incurred an OSHA-reportable incident. This exemplary safety record has been recognized by the National Safety Council and in numerous U.S. Government performance ratings and other commendations.
