Site Specific Health & Safety Plan (HASP)
Task 7 – Hazardous Waste Management: Abandoned hazardous substances will be
characterized, incompatible wastes will be segregated and compatible wastes will be
consolidated, and transported off-site for disposal. This task includes removal of hazardous
waste containers, removal of liquids and solids from subsurface structures, decontamination of
equipment used as hazardous waste management units, building walls, and surfaces, removal of
hazardous wastes identified in solid waste debris piles, collection of foundry sands, and
confirmation sampling.
Potential Hazards - Heavy equipment hazards from being struck by/against moving equipment;
being caught and injured from moving equipment parts; lifting hazards from lifting and carrying
materials; slip, fall, and trip hazards from walking on slippery and uneven surfaces; cuts, skin
abrasions, and bruises from handling of sharp tools/objects; traffic safety hazards from working
near operating vehicles and roadways; overhead utilities hazard; fire/explosion hazards from
accidental mixing of incompatible chemicals; exposures to hazardous gases/vapor and
particulates during hazardous substance removal; collapse of unstable structures, and heat stress
when working in a hot environment.
Task 8 – Subsurface/Excavation: This task involves excavation to remove impacted soil and
any work that is performed below ground surface.
Potential Hazards - Before intrusive field activities are performed, efforts must be made to
determine if underground utilities (i.e., sewers, and telephone, water, fuel, and electrical lines)
will be encountered and, if so, where such underground installations are located. The Field
Team Manager will ensure that all underground installations have been identified prior to any
intrusive operations, including, but not necessarily limited to, contacting Underground Services
Alert (USA) and compliance with Parsons Mandatory Pre-drilling Protocol. Precautions will be
exercised when working near any overhead electrical lines. A minimum safe distance will be
established by the SHSO in areas of overhead and underground power lines.
All excavation will be performed under the supervision of a competent person. Cave-ins from
unstable soil are always a concern during excavation and trenching. Barriers will be provided to
prevent persons from accidentally falling into the excavation.
An excavation or trench allowed for human entry that is deeper than 5 feet or in poor conditions
will be shored, sloped, or benched in accordance with Title 8, CCR Section 1540-41. All shoring
will be inspected daily at the beginning of the day by a competent person and after any event that
could compromise the safety of an excavation (for example, rain, heavy equipment operation
nearby, or an earthquake).
Attachment 3 contains Activity Hazard Analysis (AHA) tables.
6.2 FIVE HAZARD CONTROL MEASURES – ORDER OF
PRECEDENCE
Site hazards and hazards resulting from investigation and remediation activities are controlled
using one or more of the control measures listed below. The order of precedence is as follows:
