Recommendations

Status: Closed - No Longer Applicable
Closed - No Longer Applicable (C - NLA) - Due to subsequent events, the recommendation action no longer applies (e.g., the facility was destroyed or the company went out of business).
 

2005-3-I-NJ-2

Implement an effective Process Safety Management program, in accordance with OSHA 1910.119. Include written operating procedures and checklists that are understood by the workers responsible for using them. Train workers on the procedures and periodically confirm that they are being properly followed.
