• Do not remove, stockpile, or otherwise further disturb archeological artifacts or potentially contaminated materials; and
• Immediately notify your supervisor and wait for specific instructions prior to proceeding with work activities in the area.

Hazardous Material/Waste Handling

• Know the hazards associated with common hazardous substances prior to using them;
  
• Common hazardous materials include fuel oil, lubricants (oils), antifreeze, paints, solvents, grouting compounds, acids, and caustics;

Spills Prevention and Response

• Store hazardous materials (e.g., fuel, hydraulic and lubricating oils, paints, solvents) only in approved containers with tight fitting lids;
  
• Do not leave metal containers in direct contact with ground for extended periods (e.g., raise off ground on wood and/or underlay with plastic tarp);
  
• Report all spills to your supervisor; and
  
• Immediately prevent further spillage and contain a spill, if it can be done safely.
