Safety Policy

Simply stated, Wilhelm’s safety policy is:

  • To support this policy, Wilhelm requires compliance with the Occupational Safety and Health Act (OSHA) regulations, the American National Standard Institute (ANSI) standards, specifically ANSI Z133 and ANSI A300 standards, and the training publications distributed by the Company.

Every employee, from a newly-hired grounds-person to a top-level manager, must agree to be guided by the following principles:

  • All injuries are preventable.
  • No job or activity is worth risking injury.
  • Management is responsible for providing the environment for everyone to work safely.
  • Each individual shares in the responsibility for the safety of themselves and others.
  • We believe prevention of injuries is good business.
  • We promote off-the-job safety for our employees.
  • Safety is led by senior management, implemented by line management, with each level accountable to the one above and responsible for the one below.
  • We design and integrate safety into our management decisions.
