So my friends and i are having a halloween party, now my friends just moved into this house so we want to make a list of rules to stick to the door as you first come in so as little damage as possible ect will occur, so far all we've got is that smokers should go outside. Any ideas? (:
pros are they hold garments together temporarily or help children with their imagination. [i used to get blankets, use safety pins to make the fabric to go certain ways and design whatever was in my head. cons are if there is too much strain within the pin, it can pop open and cut you/stab you, or just lose the pin itself. also, that sometimes you have to resituate the pin, or the part that keeps the pin in/or closed.
If you are talking about HVAC systems. Most are locked into the fire alarm system to provide negative pressure in case of fire. In hospitals, industrial facilities, hotels ect. This helps clear the smoke, and reduce the spread of fire. Aiding in fire dept, response. Several air units employ this.
Pros I have to say that they are a very low priced and multipurposed tool. I use them for mending, connecting socks before I wash them, holding layers of a quilt together, jewelry etc. Cons I suppose, since people tend to lose safety pins a lot, it might be argued that it is a waste of valuable minerals, a limited resource. Also, clothes repaired carelessly with pins can look tacky. Pins carelessly dropped on the floor could be a safety hazard for small children and barefeet. Children also could choke on a safety pin.
