My site safety inspection experience

On April 1st, the Unit Safety Supervision Branch and the trade union organized a joint safety inspection, conducting in-depth checks across the site. As the unit’s security manager, I joined the inspection team and conducted a thorough evaluation of three key locations. Here's a summary of what was observed:

I. Civil Explosives Loading

During the inspection of the explosives loading area, I noticed that the safety custodian, Mr. XX, had only locked the car’s boot lock but did not secure the door after loading. I approached him and asked why he hadn’t locked it properly. He replied that since it was a short trip and not far away, it was too much trouble.

I reminded him that even if the procedure didn’t explicitly require locking, it was still his responsibility to ensure the safety of the materials. I explained that failure to lock the vehicle could result in the loss of explosives or detonators, which would be extremely dangerous if they fell into the wrong hands. He admitted he had been careless and understood the importance of following protocol.

II. Blasting Operations

Blasting is one of the most hazardous tasks in seismic exploration. Every time I conduct an inspection, I pay special attention to this operation. At the blasting site, I saw a group of workers gathered, chatting and using mobile phones and walkie-talkies. I approached the blaster and asked about the procedures for setting up the blast machine and why so many people were standing nearby.

I pointed out that radio frequency interference could cause accidental detonation, which is a serious risk. After hearing my concerns, the blaster immediately dispersed the crowd. I stayed nearby to monitor the process and observed how the operator handled the setup. He reported to the control room via intercom before triggering the blast.

After the explosion, I asked how far away from the shot point the personnel should stay. He said that currently, they kept a distance of 10–20 meters because the well was open and there was no deformation. I corrected him, explaining that the standard requires at least 30 meters. If the explosive hasn’t fully descended into the hole, there could be debris flying out. He then adjusted the distance to meet the required safety standards.

III. Labor Protection Shoes

When inspecting the work site, I noticed one worker wearing worn-out soles on his safety shoes. I stopped him and checked the condition of his footwear. It was clear that the soles were worn down, which posed a slipping risk, especially on uneven terrain. I immediately instructed the site supervisor to replace the shoes to prevent any accidents during mountain operations.

Following the inspection, we had a discussion with the site supervisor about the issue of "dumb guns" (unexploded ordnance). He mentioned that the main reason for this problem was that the shaft walls were not perfectly vertical, and the tools used were not specialized. At present, they can only rely on personal protective equipment.

I emphasized that the handling of unexploded ordnance needs more detailed procedures. We should focus on improving the accuracy of drilling, ensuring the hole is perpendicular, and providing technical data for safe processing. Drilling pipes should be measured every 20 meters, and when approaching the top 20–30 cm of the explosive charge, the drilling should stop and the charge should be detonated immediately. This is the safest way to handle such situations.

In conclusion, safety awareness must never be compromised. Strict adherence to safety procedures is essential. More emphasis should be placed on training and enforcement to eliminate unsafe practices. On-site management of civil explosives must be strengthened, and unauthorized personnel should not be allowed near the operation areas. Gathering or loitering should also be strictly prohibited.
