In the grain storage industry, safety in confined spaces within steel silos and related equipment is non-negotiable. LIAONING QIUSHI STEEL SILO CO., LTD, a global leader in innovative storage solutions, emphasizes its advanced safety protocols and cutting-edge designs to protect operators and enhance operational reliability. With a focus on preventing hazards like dust explosions and ensuring safe maintenance, the company sets a benchmark for confined space safety in grain storage.
LIAONING QIUSHI integrates state-of-the-art safety features into every silo and equipment design, prioritizing risk mitigation in high risk confined environments:
In enclosed spaces where grain dust accumulation poses a fire and explosion risk, the company equips scraper conveyors with explosion-proof motors. These motors are certified to withstand ignition hazards, reducing the risk of dust explosions—a critical safety feature in regions with strict fire safety standards. For example, in a recent project for a grain terminal in Southeast Asia, our explosion-proof systems helped the client achieve a 100% safety compliance rating.
To enhance maintenance safety, LIAONING QIUSHI installs 8mm-thick wear-resistant polyurethane linings on the inner walls of elevator chutes. This not only extends equipment lifespan but also provides a stable surface for technicians during inspections. Additionally, retractable safety ladders are integrated into chutes, allowing safe and easy access for maintenance without compromising structural integrity.
Elevator pits, often overlooked confined spaces, are fully enclosed in LIAONING QIUSHI’s designs to eliminate fall hazards. A recent installation in a North American grain facility featured reinforced pit covers with anti-slip surfaces, reducing the risk of accidents during equipment checks and cleaning.
To ensure operational safety and prolong motor life, elevator head platforms are fitted with prefabricated weatherproof canopies. These canopies shield motors from rain, dust, and extreme temperatures, minimizing electrical faults in confined spaces. In Australia’s harsh Outback climate, these canopies helped maintain 99% motor uptime for a client’s silo network.
At the head of each scraper conveyor, LIAONING QIUSHI designs extended maintenance platforms with guardrails. These platforms provide ample space for technicians to perform repairs safely, reducing the need for risky makeshift setups. A case study in Brazil showed that this feature cut maintenance time by 30% while eliminating near-miss incidents.
Beyond hardware innovations, LIAONING QIUSHI emphasizes strict operational protocols to ensure worker safety in confined spaces:
Two-Person Rule: All personnel entering silos must work in pairs, with one operator inside and a designated supervisor outside.
Fall Arrest Systems: Workers are equipped with safety harnesses and fall arrester ropes anchored to secure points. For example, in a wheat storage project in Russia, these measures ensured zero fall-related incidents during annual inventory checks.
Pre-Entry Ventilation: Ventilation systems are activated for at least 30 minutes before entry to disperse dust and replenish oxygen levels.
Air Circulation: Natural or mechanical ventilation is used to maintain safe air quality, reducing concentrations of harmful gases like carbon dioxide or mold spores.
Gas Monitoring: Before any pit work, technicians use portable detectors to measure oxygen levels (target: 19.5–23.5%) and toxic gas concentrations. In a recent project in India, pre-work gas checks identified elevated CO levels, preventing potential poisoning incidents.
“Safety is the foundation of our engineering philosophy,” says Wang Gang, Director of Safety Compliance at LIAONING QIUSHI. “Our solutions don’t just meet standards—they exceed them, combining robust hardware with operational best practices to protect both people and assets.”
The company’s commitment to confined space safety is further supported by its after-sales services, including operator training programs and annual safety audits. Clients can access 24/7 technical support to address safety concerns, ensuring continuous compliance with global regulations like OSHA (US) and COSHH (UK).
