Safety is the lifeline of the construction industry. During my twenty-year career, I have witnessed serious accidents caused by improper operation, and I have also developed a verified safety operation system. Today, I would like to share these valuable experiences gained from lessons learned.
The safety design of my equipment eliminates risks from the root. All rotating parts have fully enclosed guards, and the equipment cannot be started when the guards are not closed. There are three emergency stop buttons, located on both sides and at the rear of the operation console, and they can all be reached within one second. I designed a double-hand start device, where both buttons must be pressed simultaneously to start the cutting head. This completely eliminates the possibility of the other hand being in a dangerous area when operating with one hand. In the safety certification tests in Sweden, my equipment received the highest safety rating.
The personal protective equipment system is the mandatory standard configuration I require. I developed an integrated protective suit: cut-resistant gloves can withstand accidental contact with blades, protective masks can block flying debris, noise-reducing earplugs will reduce noise to below 85 decibels, and respirators can filter 99% of dust. In the Dubai construction site, I required operators to pass my safety equipment wearing assessment before they could start work. This strict requirement has maintained a zero-injury safety record for my clients over the past five years.
The safety assessment of the working environment is a necessary procedure before starting work. I have developed a 15-point checklist: underground pipeline detection, road bearing capacity testing, surrounding traffic control, confirmation of emergency evacuation channels, etc. In the London city center renovation project, my team spent three days conducting a safety assessment, and the actual cutting operation only took two days. The client initially did not understand, but when our operation did not cause any impact on the surrounding century-old buildings, they became my most steadfast supporters.
The control of cutting dust is a special safety aspect I pay attention to. The silica dust generated by concrete cutting is a serious health hazard. My wet dust removal system can capture 98% of the dust, and the remaining part is processed by a HEPA filter. In the tunnel project in Norway, when my equipment was working in a confined space, the air quality remained within the OSHA standards. I also equipped each piece of equipment with a real-time dust concentration monitor, which automatically shuts down and alarms when the concentration exceeds the limit.
The protection of high-temperature components prevents scalding accidents. I added insulation covers to high-temperature areas such as engine exhaust pipes and hydraulic oil pipes, with the surface temperature controlled below 50 degrees. In the summer construction in Kuwait, this design prevented multiple possible scalding accidents. I also designed an intelligent temperature monitoring system, which automatically reduces speed and alarms when any component temperature is abnormal.
The safety training system is the aspect I value the most. I provide customized training courses for each client, including theoretical teaching, simulation operations, and on-site assessments. The training materials have 12 language versions, covering all aspects from basic operations to emergency handling. In the large infrastructure project in India, I trained 200 operators, with a 100% qualification rate and zero accident rate.
True safety is not a slogan on the wall; it is a habit integrated into every operation detail. I developed a safety behavior scoring system, using cameras and sensors to record operation behaviors, automatically score and provide improvement suggestions. In the five-year project in Canada, my system reduced safety violations by 94% and insurance costs by 60%. Safety is the best benefit, and this is my unwavering belief.
