We collected cigarette butts in a range of residential areas, to assess differences in the length of unburnt tobacco in the butts, and in proportions of roll-your-own RYO cigarettes. Two high, two medium, and two low deprivation areas, as classified by deciles of the New Zealand Deprivation Index, were selected for the Wellington region. Collected butts were systematically classified and measured.

A mixed model of analysis, treating location clusters nested within deprivation level areas as a random effect, was used to assess differences in mean length of unburnt tobacco in the butts.

A total of 6, cigarette butts and separate filters were collected, of which 3, The RYO butts were not measured because of the extent of their degradation.

Deformed manufactured cigarette butts i. We found no significant difference between deprivation areas in the proportion of RYO material found. The shorter mean unburnt tobacco length in the most deprived areas is consistent with more intensive smoking among smokers in those areas.

This finding is consistent with other evidence of increased price sensitivity among poorer smokers, and with basic economic theory. Further evidence on observed smoking behavior in the field is necessary to better interpret these preliminary findings.

A shooting range , firing range or gun range is a specialized facility designed for firearms qualifications, training or practice. Some shooting ranges are operated by military or law enforcement agencies, though the majority of ranges are privately-owned and cater to recreational shooters. Supervisory personnel are responsible for ensuring that all weapon safety rules and relevant government regulations are followed at all times. Most indoor ranges restrict the use of certain powerful calibers, rifles, or fully automatic weapons.

A shooting gallery is a recreational shooting facility with very low-powered guns, often located within amusement parks , arcades , carnivals or fairgrounds that provides games and entertainments for the visiting crowd. In urban areas, most shooting ranges will be at indoor facilities. Indoor ranges offer protection from inclement weather conditions and can be operated around the clock under controlled environmental conditions. Outdoor shooting ranges are typically found away from populated areas because of concerns about safety, noise pollution and soil contamination.

Indoor firing ranges are usually constructed as standalone structures, though they may be housed in larger buildings in basement or such. Design considerations may vary depending on planned use but they all must address the basic requirements for operating the range safely, and that is provide ballistic protection, safety controls, proper ventilation, acoustic isolation and appropriate lighting.

Firing range walls are usually constructed of poured concrete, precast concrete, or masonry block. The walls must be impenetrable and provide adequate ballistic protection from stray bullets and back splatter.

Floors are constructed from dense reinforced concrete with a smooth surface finish. Floors are usually slanted slightly from uprange shooting lanes toward the bullet trap downrange to allow for better maintenance and cleaning.

Indoor firing range roofs are constructed from steel joists or precast concrete panels with a smooth flat surface that will redirect misfired bullets, facilitate maintenance, and prevent lead buildup. Roof baffles are installed at a 25—30 degree angle protect ceilings, lighting fixtures, ventilation ducts, and any other unprotected element from stray bullets.

Baffles are typically constructed of armored plate steel covered with fire-rated plywood. Deflectors are similar to baffles, but are not usually covered with plywood; they can be installed either vertically or horizontally and are used to redirect stray bullets from unprotected fixtures and elements inside the firing range such as doors, windows, and ventilation registers.

Shields are constructed of plate steel and plywood. Control rooms or stations houses the central controls for the firing range equipment, communication, lights, and security. The controls are operated by the range master—the designated official responsible for range operation and management.

The control station must provide the range master with unobstructed line of sight of the firing lanes and all shooters. Control stations are usually constructed of concrete blocks with bulletproof observation windows. Backstops and bullet traps are used to absorb the energy from the bullet and capture it to prevent overflight beyond the range area. Bullet traps come in a variety of designs and are usually constructed of impenetrable metal plates.

The thickness of the plates and the materials used depend on the velocity and energy levels of the projectiles to be fired in the range. Most modern traps consist of angled hardened steel plates that deflect the bullets into other metal plates to remove their energy. The plates must be resistant to penetration, abrasion and metal fatigue. The traps direct the spent bullets to a collection area in front of the trap or, for high-energy projectiles, at the back of the trap. Many indoor firing ranges provide additional spaces such as a cleaning room for weapons, a classroom, restrooms including shower facilities , office areas, lounge area, or storage and maintenance rooms.

Passageways are used to physically isolate the firing range from the adjoining areas. Some firing ranges are equipped with shooting booths to provide shooters with a defined firing area and to reduce potential hazard from misfires and ejected bullet cartridges from adjacent shooters. Shooting booths are made of partitions or panels which can be acoustically treated to reduce the effect of weapons discharge on other shooters. The booths are sometimes equipped with communication or target-operation equipment; target or booth lighting controls; shelves for holding weapons and bullets, or to prevent shooters from going downrange; and equipment for practicing shooting from behind a barrier.

The firing line, usually marked red or orange, runs along the downrange edge of the shooting booths. Some ranges have motion detectors that can set off an alarm when a shooter passes this line during shooting.

Target systems consist of a target, a target carrier system, and a target control system. Targets for indoor firing ranges are usually a paper sheet or piece of corrugated cardboard with a printed target image on the sheet.

The target carrier system allows the firing range to operate more efficiently and safely by transporting the target and frame between the firing line and the target line, in both downrange and uprange directions. The target control system allows the range master to control the operation and movement of the targets through a central control station in the control booth. Some firing ranges provide local control modules that can be operated in the shooting booths.

A critical component in the design and proper operation of an indoor firing ranges is the ventilation system. Supply air can be provided through a perforated wall plenum or radial air diffusers mounted at ceiling height. Airflow along the firing line should be no more than 0. Air is typically exhausted at or behind the bullet trap. Some firing ranges are designed to have multiple exhaust points downrange to maintain downrange flow and desired velocities at the firing line.

The exhaust system should be designed to provide minimum duct air velocities of The equipment and designs for the ventilation systems are varied, most firing ranges have one supply and one exhaust fan, however, some have multiple supply or exhaust fans.

Very often, the air-flow rate required by the firing range and space constraints for the fans dictate the number and types of fans. The exhaust air is always filtered before being exhausted outside the building or recirculated to the supply system.

Lighting in the range consists of control booth, uprange area, shooting booth, and downrange lighting systems. Control booth lighting is usually manually controlled and consists of general lighting and low-level lighting used during particular shooting conditions. Lighting uprange of the booths is general ceiling-level lighting and can usually be controlled manually or from the central controls. Lights downrange of the firing line are usually spotlights used to illuminate the targets at various distances downrange of the booths.

Safety control systems are installed to protect the shooters during range malfunction or emergency situations. Such systems may include warning lights, alarm bells, and air-flow and filtration monitors. Training might also specifically require exposure to the elements such as wind or rain. Outdoor competition shooting is preferred under benign weather conditions, although conditions may change, competition is only abandoned when safety becomes an issue.

Outdoor shooting ranges are designed to contain all fired shots. This necessitates a high retaining wall behind the target line called a back-stop or stop-butt, comprising an earth mound, sandbag barrier or specially designed funnel-shaped traps to catch and prevent misaligned shots, errant projectile ricochets, or shots going beyond the bounds of the shooting range. Some target-shooting ranges have separate facilities devoted to the use of higher-powered firearms such as. As its name suggests, it is generally found in military bases rather than in the more remote areas common to outdoor ranges.

Several studies of outdoor firing ranges have shown that exposure to lead and noise can cause health problems, particularly among employees and instructors. Outdoor ranges need less cleaning and maintenance than indoor ranges. However, despite the natural ventilation of outdoor firing ranges, some outdoor ranges have ballistic baffles overhead, and concrete walls and structures on the sides that can cause the air to stagnate and lead to increase exposure to lead and noise.

Consequently, operators of ranges might consider adding sound transmission barriers, absorptive materials, and natural vegetation to lessen noise emission. Fans pointing downrange can provide air movement away from shooters to lessen lead exposure. The firing point normally is at a defined point on the ground, and on a civilian range will usually be level and flat. Outdoor ranges without a covered firing point are usually grass, often on a slightly raised, flattened mound.

Outdoor ranges with a covered firing point are usually concrete or tarmacadam. Outdoor military range firing points are not usually covered and may have other configurations, e.

A "fixed firing point" or echelon [10] rifle range is where the targets are located at the various distances with the marksman or woman shooting from the one firing point. The most advanced rifle range of this design was constructed for the Commonwealth Games New Delhi The firing point cover can be as simple as a tent, to a frame with only a roof to keep off rain or sunshine to a substantial building with appropriate apertures to shoot through. Civilian targets are usually made of paper or a plastic coreflute, sometimes with a canvas or hessian back on the larger long-range types.

Most competitive targets are a solid black circle on a white background. The black circle may have scoring rings. Targets of other shapes may be used such as used in pistol hand gun target shooting. Reactive targets allow shooters to easily identify bullet strikes. This allows shooters to improve their skills by quickly being able to compare their aiming point and where the actual bullet impacted the target.

Those who choose to use military surplus rifles in competition on firing ranges at set distances include bolt and semiautomatic actions, with targets used as per military standards, current and historic.

The same applies for the matches they shoot. Other target types include a metal plate that is knocked over by the bullet such as in the air rifle sport of field target or handgun discipline of IPSC, and stationary metal plates of scaled animal outlines on which bullet strikes mark as well as those that mark the paint which is painted over again after scoring.

Outdoor and sometimes indoor ranges have earth or sand butts. Indoor ranges can use angled plates with collectors, often with a rubber curtain through which the bullet passes and is then stopped by a metal plate. Ranges without automatic target placements sometimes have concrete trenches where personnel lift and retract, mark and replace targets. They need to be of sufficient height to capture the projectile intended for the target as well as any ricochet that may occur from the projectile striking the floor of the target range fairway.

Usually the top is at least five degrees in elevation from the m firing line. Outdoor shooting ranges sometimes have wind flags, positioned between the firing line where the shooters are and the targets. Shooters observe these flags to make an estimate of wind speed, which is then converted into lateral minute of angle point of aim corrections or, alternatively, windage holdoff corrections.

The flag method is the most common method used to estimate wind speed. A flag blowing in the wind will naturally blow away from the flagpole, with the angle of the bottom of the flag to the flagpole increasing with increasing windspeed. To estimate the wind speed in mph, the angle in degrees between the bottom of the flag to the flagpole at the mid-range position between the shooter and the target is divided by 4.

The clock method is then used to determine full value, half value, or no value corrections in minute of angle for this wind. Aligning the target at the 12 o' clock position or direction, with the 6 o' clock direction being directly behind the shooter, winds at 3 or 9 o'clock are equated to full value, winds at 1, 2, 4, 5, 7, 8, 10, 11 o'clock are equated to half value, and winds at 12 and 6 o'clock are equated to no value.

The constant C equals 15 for ranges from to meters, 14 for meters, 13 for — meters, 12 for meters, and 11 for 1, meters. For full-value winds, this full windage correction is used. For half-value winds, the minute of correction in windage given by this formula is halved; for no-value winds, no minute of angle correction in windage is required.

Multiple flags are required for two reasons.
