As safe as they are installed against any surface. If installed corrected they are very safe.
Yes, you can.
Will depend on the surface. It may be nailed, secured with screws and drywall anchors, nailed with a power nailer to concrete or block, attached to bolts set into concrete, etc.
A fire rated wall is rated as such because of the material used in construction. There is specific drywall board and rated doors to obtain a fire rating. The standards are 2 and 4 hour ratings unless referring to electrical equipment.
The instructions in the box are usually decent. Just use plastic anchors for the track screws in vertical drywall surface. IF IT"S OVERHEAD mount-use the anchors that spring open once they go thru the hole for safety. Lights pretty much slide on the rail.
More to the point is how are YOU going to get wire to and from the box. Installing the box is the easy part. You first find a stud and measure the box dimensions onto it with one side almost touching the stud. Now, using a 'Keyhole' saw or drywall saw, cut out the box shape. At this point, I insert a 'fish' tape and pull the wire through, usually from the top. I pull the wire out enough to feed into the box and then push the box into the cut shape. Then screw the box into the stud obliquely, or if you've got an 'old work' box, turn the screws on the box to fix the 'ears' and secure the box. Now you can wire the outlet or switch in. -Turn off power first .
Drywall screws can typically hold around 20-30 pounds when properly installed into a wall stud.
When installing drywall, you typically cut on the side that will be facing the room or space where it is being installed. This ensures a clean and precise fit for the drywall sheets.
A drywall moisture barrier is used to prevent moisture from seeping into the walls and causing damage. It acts as a protective layer that helps to keep the drywall dry and prevents mold and mildew growth. This barrier can be made of materials like plastic or foil and is installed behind the drywall to create a barrier against moisture infiltration.
When installing drywall, you typically cut on the side that will be facing the room or space where it is being installed. This is usually the smooth side of the drywall, as opposed to the rougher side.
Baseboard should be nailed every 16 inches to the wall studs, do not nail to just the sole plate as this can allow the base to tip away where it meets the wall at the top. Most drywall has a slight bevel on the edges and when drywall is hung horizontal this bevel ends up at the floor level.
The recommended thickness of drywall for a ceiling is typically 5/8 inch. It should be installed perpendicular to the ceiling joists with the tapered edges facing down. Be sure to secure the drywall with screws or nails every 12 inches along the joists to ensure a secure installation.
Yes, you can mount a TV securely on drywall by using appropriate wall anchors and ensuring the mount is properly installed to support the weight of the TV.
When cutting drywall, you typically cut on the side that will be hidden or covered, such as the back side or the side that will be against the wall.
Square footage estimates on drywall are based on the square footage of wall and ceiling that need to be covered.
No, drywall installers do not inhale carbon dioxide from drywall. Drywall is primarily made of gypsum, a mineral that does not release carbon dioxide when installed. However, drywall dust can be a respiratory irritant, so proper ventilation and personal protective equipment should be used to avoid inhaling dust particles.
Half inch is standard unless it's separating two residences, then it's 5/8.
If you mean 50 degrees 'f' of temperature, NO I've seen it installed in much colder conditions than that.
