EU responsible person

Drone safety

• Register and fly in line with the rules where you operate. In the UK this means the Civil Aviation Authority registration requirements and the Drone and Model Aircraft Code. In the EU, register with your national aviation authority.
• Some operations, including commercial or professional work, may need additional permissions. Check the category that applies to your flight before use.
• Complete the manufacturer’s pre-flight checks before every flight, and keep the drone within your visual line of sight.
• Keep clear of spinning propellers. Remove the flight battery before handling propellers or carrying out maintenance.
• Do not fly near airports, over crowds or in weather conditions outside the manufacturer’s stated limits.
• Respect privacy. Recording people or private property may be subject to data protection and privacy laws.

Night vision and thermal device safety

• Do not point the lens at the sun, lasers or other intense light or heat sources. This can permanently damage the sensor.
• Keep the lens cap on when the device is not in use.
• Do not look into an active infrared illuminator at close range. Infrared light is invisible, so you may not notice exposure.
• When moving between cold and warm environments, let the device adjust gradually to reduce condensation.
• If the device is mounted on a firearm, make sure the firearm is unloaded before fitting, adjusting or removing it. Never use a weapon-mounted device to observe anything you do not intend to shoot.
• Laws on using night vision and thermal devices for hunting vary between countries and quarry species. Check the rules that apply to you before use.

Rifle scope and optical sight safety

• Never look at the sun through a scope, magnifier or sight. This can cause permanent eye damage.
• Make sure the firearm is unloaded and pointed in a safe direction before mounting, adjusting or removing the sight.
• Set the correct eye relief to avoid injury from the scope moving back under recoil.
• Tighten mounts and rings to the torque specified by the manufacturer, and confirm your zero before hunting or competition use.
• Never use a sight mounted on a firearm to observe anything you do not intend to shoot.

Binocular, monocular and spotting scope safety

• Never look at the sun through binoculars, monoculars, spotting scopes or telescopes. This can cause permanent eye damage.
• Do not leave the optic in direct sunlight. Lenses can focus sunlight and cause a fire.
• Do not walk or move around while looking through the optic.
• Neck straps can be a strangulation hazard. Keep straps away from young children.
• Make sure tripods and mounts are stable and fully locked before attaching the optic.

Laser rangefinder safety

• Do not look into the laser emitter, and never aim the laser at the eyes of people or animals.
• Never view the laser beam through binoculars, scopes or other magnifying optics.
• Do not aim the laser at aircraft, vehicles or reflective surfaces such as glass and mirrors.
• Check the laser class shown on the product label and follow the manufacturer instructions for safe use.
• Do not open, modify or repair the device yourself. This can expose you to hazardous laser radiation.

Laser and infrared illuminator safety

• Check the laser class shown on the product label. Lasers of Class 3R and above can cause eye injury, even from brief exposure.
• Never look into the beam or aim it at people, animals, vehicles or aircraft. In the UK it is an offence to shine a laser at a vehicle or aircraft in a way that dazzles or distracts the operator.
• Infrared lasers and illuminators emit light you cannot see, so your eyes will not blink to protect themselves. Treat an infrared device as switched on until you have confirmed it is off.
• Weapon-mounted lasers and bore sights point where the firearm points. Make sure the firearm is unloaded, and never aim it at anything you do not intend to shoot.
• Switch the device off and remove the batteries before cleaning, storing or transporting it.
• Laws on using lasers and illuminators for hunting vary between countries and quarry species. Check the rules that apply to you before use.

Torch and weapon light safety

• Do not shine the light into the eyes of people or animals at close range. High-output lights can dazzle and may cause eye damage.
• Never shine lights at vehicles or aircraft.
• Lights can become hot during use. Do not cover the lens while switched on, and use the lockout feature, where fitted, when carrying the light in a bag or pocket.
• Weapon-mounted lights point where the firearm points. Never use a weapon light to search for or identify anything you do not intend to shoot.
• Laws on lamping and using lights for hunting vary between countries and quarry species. Check the rules that apply to you before use.

Trail camera safety

• Get the landowner’s permission before installing a camera on land you do not own.
• Cameras that record people or public areas may be subject to data protection and privacy laws. Position the camera to avoid capturing people where possible.
• Take care when fitting cameras at height, and use suitable straps or mounts so the camera cannot fall.
• Cellular cameras use a mobile network connection. Follow the manufacturer’s instructions on SIM cards, data plans and account security.

Chronograph safety

• Position the chronograph so the projectile passes through the measuring area, at the minimum distance from the muzzle stated by the manufacturer.
• Make sure the firearm is unloaded before setting up, adjusting or moving the chronograph. Never go downrange while anyone is shooting.
• Always use a safe backstop, as the chronograph does not stop the projectile.
• Wear eye protection. Fragments from a struck unit or support can cause injury.

Smartwatch and GPS device safety

• Do not rely solely on the device for navigation or ballistic data in hazardous conditions. Always carry a backup and check the data yourself.
• Stop wearing the device if you notice skin irritation.
• Follow the manufacturer’s water resistance rating and charging instructions.
• Health and fitness readings are for guidance only. The device is not a medical device.

High-pressure air safety

• Wear eye protection when reloading, priming or decapping.
• Keep powder and primers away from heat, sparks and naked flames. Do not smoke while reloading.
• The purchase and storage of powder and primers is legally controlled. Check the regulations and certificate conditions that apply to you.
• Lead and cleaning media dust can be harmful. Work in a well-ventilated area, do not eat or drink while reloading, and wash your hands afterwards.
• Keep reloading equipment and components away from children.

Air gun pellet safety

• You must be 18 or over to buy air gun pellets in the UK.
• Most pellets contain lead. Wash your hands after handling, and do not put pellets in your mouth.
• Keep pellets away from children and pets. If a pellet is swallowed, seek medical advice.
• Always use a safe backstop, and make sure you know what is beyond your target.

Target safety

• Always use a safe backstop capable of stopping the projectiles you are using.
• Check the minimum safe distance and maximum power or calibre stated for the target. Steel and reactive targets can cause ricochets and fragments.
