Control measures for carbon dioxide gas blasting

In all construction projects, safety cannot be guaranteed that it will definitely not occur. Compared with traditional explosives, carbon dioxide blasting is safer. Only by controlling the safety of the hazard sources of carbon dioxide explosions can accidents be prevented. Now, follow Chuangpuda to learn about carbon dioxide blasting:

1. Mechanical injury control measures

(1) All personnel using various types of mechanical equipment must undergo technical training and pass the assessment by relevant departments before they can take up their posts. Unlicensed operation is strictly prohibited.

(2) All types of machinery users should be equipped with the performance and safety devices of the machinery they operate. Be familiar with safety regulations and be capable of troubleshooting common faults and conducting daily maintenance.

(3) During work, staff members must wear protective equipment, concentrate their minds, follow instructions and operate carefully. Without permission, one must not leave the post without permission and must not hand over the machine to others.

(4) The mechanical equipment transported to the site should have good performance, complete protective devices, and spare parts required for production and safety. It can only be used after being approved by the equipment department and the on-site supervisor.

(5) When motor vehicles are in motion or parked, they must maintain a certain safe distance from ditches, foundation pits and power transmission lines.

(6) When carbon dioxide blasting machinery and equipment enter the operation site, the person in charge of the unit project should explain the operation tasks and safety technical measures in detail to the operators.

2. Object strike control measures

(1)After each carbon dioxide blasting is completed, the floating stones at the top edge of the slope and the steps should be cleared in a timely manner.

(2) When working under a slope, it is necessary to first check whether there are loose rocks and cracks on the slope. Before starting the operation, the pumice stones and slope cracks should be cleared.

(3) When someone is working at the top of the slope, no one is allowed to work directly above the area where there are workers below.

(4) When working on slopes, the loose rocks within the movement range of the safety rope should be cleared.

(5) Operators must wear safety helmets.

The above is all the content points about carbon dioxide blasting that Chuangpuda shares with you this time. We hope you can have a brand-new understanding of it.
