Michael Jackson went 60 days without real sleep

Michael Jackson died while preparing to set a world record for the most successful concert run ever, but he unknowingly set another record that led to his death.

Jackson may be the only human ever to go two months without REM - Rapid Eye Movement - sleep, which is vital to keep the brain and body alive. The 60 nights of propofol infusions Dr. Conrad Murray said he gave Jackson to treat his insomnia is something a sleep expert says no one had ever undergone.

“The symptoms that Mr. Jackson was exhibiting were consistent with what someone might expect to see of someone suffering from total sleep deprivation over a chronic period, ” Dr. Charles Czeisler, a Harvard Medical School sleep expert, testified Friday at the wrongful-death trial of concert promoter AEG Live, company that hired Dr. Conrad Murray as Jackson's personal physician.
Propofol disrupts the normal sleep cycle and offers no REM sleep, yet it leaves a patient feeling refreshed as if they had experienced genuine sleep, according to Czeisler.
If the singer had not died on June 25,2009, of an overdose of the surgical anesthetic, the lack of REM sleep may have soon taken his life anyway, according Czeisler's testimony Friday.

1. Introduction

Fires are the accidents which occur most frequently, whose causes are the most diverse and which require intervention methods and techniques adapted to the conditions and needs of each incident. Depending on the type of fire (nature of the material ablaze), meteorological conditions (wind) and the effectiveness of the intervention, material damage can be limited (a single car, building or production or storage warehouse installation), or affect wide areas (forest or agricultural fires, hydrocarbons, gas or other highly flammable products, storage or piping installations, harbour installations and rail or marine transport equipment).

2. Preventive and protective measures

Fires can spread more or less rapidly depending on their causes, the nature of the material and goods alight, the fire prevention installations (automatic sprinklers), meteorological conditions, the ways the population is informed and the initiative it shows, as well as the speed and efficiency of the intervening services and of their fire-fighting equipment. In the light of experience, prevention is seen to be most important and consists of two distinct components. On the one hand, the primary responsibility falling upon the political authorities empowered to implement the legal prescriptions concerning fire protection, to forecast accidents and to inform the population, as well as to set up measures and means for fighting fires and explosions. On the other hand, the responsible behaviour of each individual based upon an education geared towards caution and the respect of instructions in case of fire. Defining, and controlling the implementation of, the particular rules of protection against fires, specific to each enterprise presenting a potential danger, including the training of security personnel, is also relevant in this context. The many types of fire and the preventive and protective measures which relate to them, make it advisable to limit the present study to the specific measures falling to the political authorities in one area only, namely that of “forest fires”. This type of fire is of particular interest to developing countries and the preventive measures to be applied have a general representative value, that is:

– organising an observation service, prevention and alarm (security) service at local and regional levels;

– implementing legislation regulating the use of fire by all the population present in or at the edge of forests, and more particularly by owners and individuals exercising a professional activity in sensitive areas;

– planning and concrete preparation (periodic maintenance) for fire-fighting through adequate landscaping of the territory and appropriate forest cultivation limiting fire propagation (alternating vegetation, clearance, trimming), creating and maintaining access paths (extinction) and fire-break areas as well as fire-fighting equipment such as water supplies (conduits, cisterns), watch towers and meteorological posts, and the construction of helicopter landing pads;

– surveillance and detection of fires as soon as the danger of fires is forecast by the ad hoc meteorological service (which comprises automatic or mobile statistics posts observing the winds and the vegetation: dryness, force, direction, evolution);

– as soon as the danger of fire increases, activating an alarm plan (basic intervention plan) requiring the engagement of preventive intervention squads (firemen), and their wide positioning as near as possible to the threatened zones, and making available water bombers and specialised aerial machines ready for action;

– preparation and concretisation (organisation) of an intervention mechanism: this requires the setting up of specialised management programmes ensuring the coordination of powerful and efficient equipment and means for fighting forest fires (instruction);

– preparedness management and the coordination of the use of the means of intervention of the authorities and the information and alarm services for the population require a secure transmission network (radio network);

– planning the evacuation of the population possibly under threat in the various sensitive areas, particularly if there are risks of explosion (reservoirs and gas conduits explosives or ammunition dumps, hydrocarbon production, handling or transport installations, other dangerous material, etc.).
