Combustible dust is a serious yet often overlooked hazard in many industrial facilities.  Juexin is one of the few authorised consultancies in South Africa qualified to conduct and certify Dust Hazard Analyses (DHA), in alignment with NFPA 652 and other relevant NFPA standards.

• We perform on-site assessments to:
• Identify potential ignition sources and dust accumulation points
• Evaluate equipment and process safety
• Recommend engineered solutions to mitigate explosion risks

Our DHA services are essential for industries such as food processing, woodworking, pharmaceuticals, and mining—ensuring legal compliance and operational

A well-designed evacuation strategy can mean the difference between order and chaos during an emergency.  Juexin develops Fire Emergency Evacuation Plans (FEEP) tailored to each facility’s layout, occupancy type, and risk profile.

Each plan includes:

• Clearly marked evacuation routes and floor maps
• Assembly points and role assignments
• Emergency response actions and communication procedures
• Time-based evacuation modelling to validate egress feasibility

We incorporate human behaviour analysis and performance-based design to ensure realistic, efficient, and code-compliant evacuation outcomes.

Understanding fire risk is the first step in effective fire protection.  Juexin conducts detailed Fire Hazard and Risk Assessments, considering:

• Building occupancy and use
• Fire load and materials
• Detection and suppression capabilities
• Human factors and accessibility
• Business continuity needs

Our assessments form the foundation for designing tailored fire safety strategies that are proportionate to risk, regulatory requirements, and client priorities. Whether for a new development or an existing facility, our goal is to enhance resilience while maintaining operational feasibility.

Juexin provides end-to-end design services for all types of fire protection systems, divided into:

Passive Fire Protection:

Includes fire-rated walls, floors, doors, coatings, compartmentation, and firestopping—designed to limit fire spread and maintain structural integrity.

Active Fire Protection:

Involves systems that detect and suppress fires, such as:

• Automatic sprinkler systems
• Fire detection and alarm systems
• Gas suppression and mist systems
• Fire hydrants and hose reels

Our fire protection system designs are fully integrated with architectural, mechanical, and electrical components to ensure seamless performance, easy maintenance, and long-term cost-effectiveness.

Traditional risk assessments are often deterministic, assuming worst-case scenarios.  Juexin adds value by applying probabilistic modelling, using:

• Custom probability distributions for fire initiation and development
• Risk quantification tools to evaluate likelihood and consequence
• Statistical comparisons of various mitigation strategies

This enables clients to make informed decisions grounded in data and real-world likelihoods—particularly useful for high-value, mission-critical, or insurance-sensitive facilities.

Under SANS 10400-T, Rational Design offers a performance-based alternative to conventional compliance.  Juexin’s fire engineers develop Rational Designs that:

• Demonstrate code equivalence through scientific analysis
• Tailor safety strategies to specific building features and risks
• Justify innovative or unconventional designs

This service is especially valuable for large-scale commercial, high-rise, mixed-use, and industrial developments that fall outside prescriptive code parameters.

Many environments contain sensitive equipment, critical infrastructure, or volatile materials where traditional water-based fire suppression could cause more damage than fire itself.  For these high-risk areas, Juexin designs and implements tailored special hazard suppression systems using:

• Clean agents like FM-200 and inert gases (e.g., Argon, Nitrogen)
• Carbon dioxide (CO₂) systems for electrical and enclosed hazards
• Water mist systems offering fine droplet cooling without water damage
• Foam suppression for hydrocarbon and flammable liquid fires
• Deluge systems for high-hazard open areas and process equipment.

Our solutions ensure fast, effective suppression while preserving property and business continuity.
