Safety Guidelines

5.5 - Traffic

Many times the well is constructed in a high traffic area such as a retail service station. The traffic control

plan developed for the drilling operations should also be used for the well construction, development, and

abandonment phases of the project.

5.6 - Housekeeping of Bagged Material

Filter pack, transition sand, cement, and high solids bentonite grout are normally packaged in paper bags

weighing between 50 lbs and 100 lbs. Many times the bagged material is stored on the project location in

inclement weather conditions. Rain and sunlight can and will degrade the packaging material which leads to

breakage and spillage of sand, gravel and grout material. Additionally, the bagged material must be stacked

in a manner which is safe for personnel moving the sacks.

The following sections detail the steps used in well construction activities along with potential hazards of

the operations.

5.7 - Transport Well Materials to Location

Prior to the movement of materials to the well location the following items will need to be considered:

• Distance from supply vehicle to the well location

• Weight, size and length of the materials

• Site terrain and pathways

• Method of movement and equipment to be used

5.7.1 - Well Casing and Annular Materials

Movement of the well casing material (PVC, Stainless) and annular materials (filter pack, seal materials and

cement or grout) may involve the use of manual or mechanical handling methods such as:

• Forklift

• Manually (PVC screen and casing, individual bags of gravel, sand and grout)
