Millstone Weber Safety Programs

In the pursuit of continuous workplace safety improvement, Millstone Weber has implemented several programs and procedures to ensure that every employee is equipped with the knowledge and resources to maintain a safe and healthy working environment:

Alcohol and Drug-Free Workplace Program

Every employee participates in our Alcohol and Drug-Free Workplace program. Supervisors also receive Drug & Alcohol Awareness training for Reasonable Suspicion.

New Employee Orientation Program

Each new employee receives an intensive new employee orientation that covers company safety policies and procedures, followed by a written test to demonstrate their knowledge and understanding.

Training & Certification Programs

All construction superintendents and project managers receive the OSHA 30 hour training and an annual eight hour refresher course on various safety topics and company policies. The Safety Department also conducts frequent safety meetings on each of our projects addressing site specific issues. Certification programs include Qualified Forklift Operator, Flagger Certification, Excavation Competent Person, Qualified Signal Person, Qualified Rigger, First Aid / CPR, and Fall Prevention & Protection Competent Person & Equipment Inspection training.

Subcontractor Compliance

The belief in protecting employees also extends to subcontractors through training sessions on Millstone Weber policies and procedures. Subcontractors are thoroughly evaluated, continuously monitored for safe practices, and carefully reviewed prior to establishing new contracts.

Safety Inspections

Jobsite superintendents perform daily inspections in addition to their monthly comprehensive documented inspection. Safety department personnel conduct regular “Walkthroughs” on all job sites.

“Near Miss” Incentive Program

MW believes in advancing safety by learning from experience. One of our most beneficial tools is the Near Miss reporting procedure where even incidents that did not result in damage or injury — but potentially could have — are reported, allowing the incident to be investigated and corrective actions taken before any potential incidents occur.To encourage the use of the Near Miss Program, a $250 “Near Miss of the Quarter” award is presented to the near miss selected by the safety committee members that provides the most proactive preventative measure. A $1,000 “Near Miss of the Year” award is presented to the near miss selected by the safety committee members of the four quarterly winners.

Annual Safety Incentive Award

This program encourages and rewards employees to perform their work in a safe manner to prevent injuries to themselves and all fellow employees. All employees working a minimum of 1,000 hours are eligible for an annual safety incentive award. To maintain their eligibility, employees must follow established safety policies, report all incidents in a timely manner, and work in a manner that prevents personal injury.
