Store features also help alleviate the trauma of clothes shopping, including faraway mirrors, quick-burning clothes (for those unsure about wearing it), and knock-out gas if a customer spends more than 30 seconds in the dressing room (a big, strong bodyguard will finish the shopping for the unconscious customer).
Burning mirrors achieve a similar effect by using reflecting surfaces to focus the light. They were used in 18th-century chemical studies for burning materials in closed glass vessels where the products of combustion could be trapped for analysis. The burning glass was a useful contrivance in the days before electrical ignition was easily achieved.
The Joint Code of Practice provides advice on how to prevent fires such as through the use of flame-retardant temporary protection materials: for example, some high quality floor protectors are designed to burn slowly and prevent the spread of fires.
Electrical burn on hand. An electrical burn is a burn that results from electricity passing through the body causing rapid injury. Approximately 1000 deaths per year due to electrical injuries are reported in the United States, with a mortality rate of 3-5%.
A cap, hood, or shroud serves to keep rainwater out of the exterior of the chimney; rain in the chimney is a much greater problem in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, which soaks up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the crown or ...

A tall chimney contains the spent gases above the flame. If the percentage of firedamp starts to rise, less oxygen is available in the air and combustion is diminished or extinguished. Early Geordie lamps had a simple pierced copper cap over the chimney to further restrict the flow and to ensure that the vital spent gas did not escape too quickly.
Phantosmia (phantom smell), also called an olfactory hallucination or a phantom odor, [1] is smelling an odor that is not actually there. This hallucination is intrinsically suspicious as the formal evaluation and detection of relatively low levels of odour particles is itself a very tricky task in air epistemology.
