A hazard in Star Trek Online is an area-of-effect left behind by an ability that cause damage or some other effect on a periodic basis, but only if you remain within the affected radius. This is in contrast to a DoT; players and NPCs can move away from hazards, but not DoTs.

Ground hazards

• Plasma Grenade - Causes small AoE kinetic damage, but also leaves a plasma damage hazard at the point of detonation.
  • Cryonic Grenade - A specialty grenade that partially ignores shields, causing kinetic and cold damage and leaves a freezing hazard.
• Smoke Grenade - Increases ally stealth; reduces enemy perception
• Exothermic Induction Field - Creates a fire damage hazard.
  • Research Kit Module - Endothermic Induction Field - Creates a cold damage hazard.
• Seismic Agitation Field - Creates a kinetic damage hazard that knocks those in range toward the center, and causes them to stumble.
• Mechanic Kit Module - Molten Terrain - Creates a fire damage hazard.
• Enhanced Crawler Mine from the Na'kuhl Temporal Operative set leaves a toxic damage hazard

Used by enemies:

In space combat, Hazard Emitters will shield you from the effects of hazards for its duration. The vast majority of abilities that cause hazards deal damage based on your Exotic Particle Generator (EPG) skill, with exceptions noted below.

Note that abilities such as Destabilizing Resonance Beam are channeled, and so while they affect enemies within a radius of the target, they are not considered hazards.

• Coolant Ignition
  • Reinforcements Squadron's Kolvoord Starburst
• Create Fluidic Rift from the Fluidic Conduit Projector
• Trait: Delphic Shockwave - Delphic Expanse Anomaly Radiation damage hazard when using Photonic Shockwave
• Eject Tetryon Plasma from the Tetryon-Plasma Impulse Engines lowers speed and turn rate, and disables cloak. Does not deal damage.
