What safety facilities should a well-digging construction team be equipped with

To ensure operational safety, the well drilling construction team needs to be equipped with a series of safety facilities, which can be mainly divided into the following key categories:

I. Personal protective equipment

This is the basic line of defense to ensure the safety of operating personnel. All personnel entering the construction site must wear safety helmets, puncture-resistant insulated rubber shoes, and protective gloves. When conducting operations inside wells, personnel must wear safety ropes (belts) and be equipped with emergency rope ladders for quick evacuation in case of emergency.

II. Wellhead and anti-falling facilities

The wellhead is an area with a high concentration of risks. After the wellbore is completed, the wellhead should be equipped with a fence that is at least 0.3 meters above the ground and a sturdy protective railing. At night, a red warning light should be hung. Lifting systems such as winches and drawworks must be installed with reliable limiters and anti-unhooking devices to prevent accidental falls of buckets or tools. The wellhead also needs to be equipped with a sturdy protective cover plate to cover the wellhead during non-operating periods.

III. Electrical safety equipment

The temporary power system at the construction site must be strictly regulated. It should adhere to the "three-level power distribution" principle (main distribution box, sub-distribution box, switch box), and strictly enforce the regulation of "one machine, one switch, one leakage protector". Each electrical equipment should have an independent switch and leakage protector. The metal casings of all electrical equipment and circuits must be reliably grounded. Lighting inside the well must use safe voltage (such as portable lights with a voltage below 36V).

IV. Ventilation and gas detection equipment

For wells with a depth exceeding 6 meters or potential presence of harmful gases, mechanical forced ventilation equipment must be employed to continuously supply fresh air underground. Prior to workers descending into the well and throughout the operation, portable multifunction gas detectors must be utilized to monitor the concentrations of critical gases such as oxygen, methane, carbon monoxide, and hydrogen sulfide. At certain key locations, the installation of fixed gas monitoring systems can also be considered to facilitate real-time remote surveillance.

V. Fire Protection and Emergency Facilities

The construction site should be equipped with fire extinguishers according to the scale of operations and as required, and set up clear safety warning signs such as "No Open Flames". The site should be equipped with basic emergency rescue equipment such as first aid kits and stretchers, and ensure that on-site personnel are familiar with emergency procedures.

VI. On-site Management and Warning Facilities

The construction area should be isolated from the surrounding environment using enclosed fencing with a height of not less than 1.8 meters. Prominent safety warning signs should be set up in hazardous areas (such as near mud pits and electrical distribution boxes). Large equipment such as drilling rigs must be firmly supported, and rotating parts such as fans and chains must be equipped with protective covers.

A reliable well-drilling construction team is not only well-equipped, but also strictly adheres to safety procedures. Through systematic management and training, they ensure that every safety facility truly functions.
