The PROM-1 may have a visually identifiable trip wire or extended fuze assembly. The mine's large metallic content makes it easy for hand-held mine detectors to identify.
The smooth, bottle-shaped body has a threaded fuze well at the top and is internally ringed for enhanced fragmentation. Down the center of the mine is a tube containing 3 g of propellant, which leads into a chamber in the base plug. The base plug, which is attached to the main body by brass screws, holds the tether wire spool of the detonating fuze assembly. Two base plug variants exist. The remainder of the detonating fuze assembly is set inside the main charge, to one side of the central tube. During transit the initiating fuze well is sealed with a brass plug and rubber O-ring.
The UPROM-1 fuze has an internal firing pin and an explosive output. The fuze has four prongs for pressure actuation and a central spigot with a small ring for trip-wire attachment. The ring is free to rotate and can be used with multiple tripwires. A special safety collar is used to secure the prong assembly during transit.
The mine is usually supplied with two rolls of plastic coated tripwire each 53 ft (16 m) long.
The mine may be planted in water up to 20 in (500 mm) deep.
The PROM-1 is activated by tilting the prongs at the top of the fuze. This can be done by direct pressure or by pulling a tripwire. On initiation, the mine body is thrown into the air leaving the base plate in the ground. The body is tethered to the base plate with a 3-ft (1-m) long wire. When the wire is pulled tight, that initiates the main charge and the body of the mine fragments in a 360-degree radius.
The APERS mine body and fuze are olive drab. Markings on the fuze are black and yellow on the mine body. The practice mine is also olive drab with a yellow band around the mine body and fuze nut. Markings are black.
Bosnia-Herzegovina reported in May 2010 that it retained 162 PROM-1 mines, without fuzes, for training purposes.

Successful clearance of the PROM-1 anti-personnel mine has included the use of line charges, individual clearing charges and mine plows (by detonation). Explosions from other land mines may activate the PROM-1's radial-pull fuze.
This is one of the six most common mines found in Bosnia.
The fuze can be neutralized by putting the safety collar around the fuze spigot and pushing the wire loop down against the fuze body. Remove the fuze by unscrewing it from the body to neutralize the mine. Then screw the brass transit cap into the fuze well.
Since the mine's detonator is fixed inside the body of the mine, it cannot be completely disarmed.
