Quantifying Static Electricity Hazard with High Explosives

In summary, it is important to handle explosive mixtures with care to avoid static electricity induced detonation and to follow detailed codes for the manufacture of fireworks. It is not a good idea to store explosives in plastic containers as there is a risk of static buildup. It is recommended to consult these codes rather than seeking advice from strangers on the Internet.

In the making of firework explosives, the explosive mixtures are handled with great care to avoid static electricity induced detonation of the explosives. Is it a good idea that they store the explosives in a plastic container - isn't there a risk of static buildup that could detonate the explosives?

There are detailed codes for the manufacture of fireworks. I urge you to consult those rather than ask strangers on the Internet.

Sorry, But I don't have a link to the code.

I was surprised at a few thing in the video... No antistatic wrist straps? Man wearing a sweatshirt made of ?? rather than an antistatic overall?

Yeah, no kidding. Darwin Award applicant in the making, IMO.

Good advice. :smile:
 

1. What is static electricity hazard?

Static electricity hazard refers to the potential danger posed by the accumulation of electric charges on the surface of or within materials. This can result in sparks or discharges, which can ignite flammable materials or sensitive explosives.

2. How is static electricity quantified?

Static electricity can be quantified by measuring the amount of electric charge present and the potential difference between two points. This is typically done using specialized equipment and techniques, such as the Faraday Cage test or the use of electrostatic discharge (ESD) meters.

3. What role does high explosives play in static electricity hazard?

High explosives are highly sensitive to electrostatic discharges, making them more susceptible to ignition by static electricity. Additionally, the production and handling of high explosives can generate significant amounts of static electricity, increasing the potential for accidents.

4. How does weather affect static electricity hazard with high explosives?

Weather conditions, such as humidity and temperature, can greatly impact the amount of static electricity that builds up on surfaces and materials. Lower humidity and higher temperatures can increase the risk of electrostatic discharges, making it important to monitor these factors when handling high explosives.

5. What measures can be taken to mitigate static electricity hazard with high explosives?

There are several steps that can be taken to mitigate the risks associated with static electricity hazard and high explosives. These include grounding and bonding equipment and materials, controlling humidity levels, avoiding the use of materials that generate static electricity, and following proper handling and storage procedures. It is also important to regularly monitor and test for any potential electrostatic hazards.
