Expert WitnessLitigation Support
The Engineers Collaborative provides expert professional consulting, engineering, and design services for industrial ventilation systems, dust collection and control systems, and vapor control systems to help protect employees' health and plant facilities. We utilize current technologies incorporating lev hoods, dust control hoods, vapor control hoods, local industrial exhaust systems, dust containment booths, dust explosion protection, and dust filtration systems.


The Engineers Collaborative provides expert engineering consultancy and design solutions for industrial ventilation systems for combustible dust collection, dust control and vapor control systems:

* Surveys and troubleshooting for existing industrial ventilation, industrial exhaust, dust collection systems, and dust and vapor control systems.

* Pre-design cost estimates for new or upgraded industrial ventilation systems including dust collection and vapor control exhaust systems.

* Engineered solutions that reduce and contain dust and vapors by recommending process changes, thereby minimizing costs.

* Ventilation designs that get the most out of your existing industrial ventilation systems, at a minimum cost.

* Consulting and the design of new industrial exhaust and industrial ventilation systems including custom dust control, dust collection, and vapor control hoods, booths, ductwork, cyclones, dust collectors, combustible dust containment devices, and industrial ventilation exhaust fans.

* Meet the OSHA exposure limits for airborne contaminants for a safer industrial working environment.

* On-site surveys and problem-solving to help mitigate OSHA citations related to dust collection systems and combustible dust issues.

Licensed Professional Engineer in New York, New Jersey and Pennsylvania.

Legal Experience & Services

1) Reviewed existing plant dust control exhaust systems and provided the design criteria for silica dust control for a brick manufacturer. The manufacturer was challenged by OSHA to provide full engineering controls in lieu of PPE (personal protective equipment). Worked with the client's attorney in preparing solution documentation eliminating the need for full engineering controls.

2) Consulted with attorneys involving the cause and responsibility for a plant combustible chemical dust explosion that caused multiple employee injuries and deaths.

3) Consulted with attorneys involving the cause and responsibility for a combustible metal dust ignition from a dust collector that caused serious injury to a plant employee.

4) Consulted with attorneys involving the cause and responsibility for a plant food dust explosion that caused multiple plant employee injuries and deaths.

5) Consulted with attorneys involving the cause and responsibility for the injury to a plant employee caused by unguarded rotating equipment.

6) Consulted on a number of OSHA citation issues related to combustible dust at various manufacturing plants. Worked directly with clients and attorneys to satisfy OSHA requirements at the least possible cost.

7) Consulted with attorneys involving the cause and responsibility for the injury to an individual caused by fume-generating operations on an adjacent floor of a multi-story facility.

Link Combustible Dust: How to Safely Handle It

Combustible dusts pose a deflagration or other fire hazard when suspended in air. Deflagrations can lead to explosions. Combustible dusts are often either organic or metal dusts that are finely ground into very small particles. Types of dusts include, but are not limited to: metal dust, such as aluminum and magnesium; wood dust; plastic dust; biosolids; organic dust, such as sugar, and paper. Some industries that handle combustible dusts include: agriculture, chemicals, textiles, forest and furniture products, wastewater treatment, metal processing, paper products, pharmaceuticals, and recycling operations (metal, paper, and plastic).
