The GreenGrid^® business follows WESTON’s safety program. WESTON is a world-class leader in safety and is committed to Safety First in all aspects of its operations. All of our installers are trained in accordance with the applicable OSHA standards, a particularly important aspect when working on roofs. In addition, since the GreenGrid^® modules arrive at the roof preplanted, there is less time required for roof installation than with traditional built up green roof systems.

WESTON’s corporate Environmental Health and Safety (EHS) program is proactive in assessing current and projected EHS needs and setting strategies to meet anticipated requirements. WESTON’s EHS program fully complies with these standards:

• OSHA 29 CFR 1910.120

• 29 CFR 1926.65(b)

• USACE EM 385-1-1 requirements

• All related OSHA General Industry and Construction Standards, Department of Transportation, and EPA regulations

WESTON’s adherence to EHS legislative and regulatory requirements, and the high-level commitment of WESTON’s senior management team to the EHS program, sends the powerful message that WESTON takes all EHS concerns seriously. WESTON utilizes integrated EHS management systems to implement its corporate goal to have 100% of its employees and subcontractors working safely 100% of the time.

Two traditional benchmarks for evaluating WESTON’s EHS Program performance are the workers’ compensation experience modification rate (EMR) and the OSHA-Recordable Incidence Rate (ORIR):

• WESTON’s 2006 EMR of .42 is 58% better than the average for all companies similarly classified.

• WESTON’s ORIR is also outstanding, decreasing from 3.29 in 1998 to .92 in 2005.
