A safe distance from a supernova explosion would be millions of light-years away. The energy and radiation emitted during a supernova event are extremely powerful and can have destructive effects on planets and other celestial bodies nearby.
Safety distance from an active volcano's explosion varies based on its size and type. Generally, a distance of at least 6 miles (10 kilometers) is considered safe for large volcanic explosions. However, it's essential to follow advice from local authorities and evacuation orders to ensure safety.
Well it depends on what kind of firework it is. If its a 1.4G firework you should have the crowed at least 10-40 yards away but if the type of firework is 1.3G you should have the crowed 30-60 yards away. I dont know if this is correct but that is what i know if the changed the regulations then I am not aware of or if the lenght is to long.
A safe distance between mooring buoys for boats of 15 meters in length would typically be around 15-20 meters. This distance allows for enough space for boats to swing with changing winds and currents without risking collisions with neighboring boats or buoys. It's important to also consider the specific conditions of the mooring area when determining the appropriate distance.
No, it is not safe to puncture an empty aerosol can. Even if the can appears empty, there may still be residual propellant inside that can be released when punctured, potentially causing an explosion or injury. It is best to dispose of empty aerosol cans properly.
A distance less than one mile is typically referred to as a "short distance." It may be easily walkable or a quick drive.
The minimum distance a flammable storage locker is required to be from an explosive location varies by jurisdiction and regulations. Typically, a safe distance is around 50 feet to minimize the risk of fire or explosion. It is important to consult local regulations and codes to determine the specific distance required in your area.

About 50 to 100 light-years as the closest safe distance between Earth and a supernova. But, if a supernova to go off within about 30 light-years of us, that would lead to major effects on the Earth, possibly mass extinctions.
Safety distance from an active volcano's explosion varies based on its size and type. Generally, a distance of at least 6 miles (10 kilometers) is considered safe for large volcanic explosions. However, it's essential to follow advice from local authorities and evacuation orders to ensure safety.
The external irradiation from depleted uranium is not significative.
The minimum withdrawal distance for an explosive such as HCD 1.4 involved in a fire is generally determined by the relevant safety regulations and guidelines, as well as the specific characteristics of the explosive. A safe distance should be established based on the potential hazards presented by the explosive in a fire scenario to protect individuals and property from the risks of explosion or fragmentation. Consulting with local authorities or explosive safety experts is recommended to determine the appropriate withdrawal distance in specific situations.
