  • Collaboration with NIOSH on Contractor Safety Management

    To ensure a safe and healthy workplace for all employees, visitors, and contractors, SilTerra has engaged the National Institute of Safety and Health (NIOSH) to provide occupational health and safety (OHS) training and certification for all contractors performing physical work in the premises (referred to as Contractor Safety Passport system - CSPS). This is in addition to the in-house EHS briefing, which is designed to inform the contractors of the emergency preparedness and response procedures, housekeeping practices, as well as environmental conservation requirements.

    By engaging NIOSH in OHS training and certification, a uniform standard among all participating industries can be achieved, at minimal cost to the contractors, but enormous returns by absence of liabilities arising out of untoward incidents. Contractors will be given an identification badge, denoting their certification in general and/or specialized OHS safety certification. Recently, with collaboration with NIOSH and other factories, SilTerra has contributed to the upgrading of the CSPS program on as follows;

    Certification duration extended from 1 year to 2 years General OHS training and certification includes multiple disciplines, previously separated, benefiting the bulk of contract workers. Disciplines, elected are frequent scenarios observed in factories, are ;

    • General Safety
    • Material Handling
    • Basic Chemical Handling
    • Housekeeping
    • Landscaping
    • Catering

    By ensuring all contractors equipped with basic knowledge on OHS, the workplace is secured from unwanted incidents that could lead to business liability. SilTerra adopts this principle to ensure a productive workplace and a profitable organization.
