Controlling the Hazards: Parts, Sparks, and Strokes 

This presentation will focus on the collaborative efforts between users, facilities, IH and Safety Professionals in an effort to mitigate potential hazardous exposures, as well as potential compliance issues when using 3D printers. Many times, we tend to put hazards into the simple context of can I see it, can I smell it, or can I feel it. However, static electricity typically eludes our routine mindset. The critical points of bonding, grounding, controlling the velocity of the liquid within the transferring mechanism, minimum ignition energy, and splash filing all contribute to the static electricity environment and all must be effectively controlled. In this session, we will discuss the hazards and controls associated with these points as it relates to the transfer/loading of bulk flammable liquids. A primary function of an indoor pool ventilation system is to remove gaseous disinfection by-products (DBPs). Chloramine compounds are of particular importance. A project was conducted at a Seattle Public Pool to assess the effectiveness of a supplemental ventilation system that removes air from a location proximal to the pool. The system, intended to be more effective at removing DBPs, than the general ventilation system, could potentially reduce energy consumption. ​

Weld Fume Safety: Engineering Controls vs. Personal Protection 

Engineering controls such as ventilation or dust collection are the first line of defense to protect workers from toxic weld fume exposure. We'll sort through the pros and cons of different approaches to fume and dust mitigation. The session will cover: OSHA standards, engineering controls, evaluating the effectiveness of engineering controls, and personal protection options. How to balance efficacy, energy efficiency, operator comfort and safety will be discussed.​

Dust Explosions: The Problem, Control Measures & the New NFPA 652 

This session will discuss a well-tried approach to identify, assess, and eliminate/control dust explosion hazards. This presentation will provide the attendees with the ability to screen materials and the precautions that should be taken in handling, processing, and storing combustible powders. Various types of ignition hazards and the severity of combustion incidents will be discussed. This session will include the requirements of the New National Fire Protection Association (NFPA) 652: "Standard on the Fundamentals of Combustible Dusts".​

 ​​Flash Fire and Explosions Caused by Electrostatic Discharges 

Electrostatic charge is normally generated whenever two materials (solids and/or liquids) make and then break contact. Electrostatic charge generation is expected during operations such as liquid and powder flow through piping, hoses, and chutes, agitation/mixing, and filtration. Electrostatic discharges can ignite flammable atmospheres and cause pinholing of piping and vessels. This presentation will discuss the conditions under which electrostatic charges can generate, accumulate, and cause incendive discharges. Practical techniques for identifying, quantifying, eliminating and controlling electrostatic ignition hazards will be presented.​
