Ra gen-engineering-12 [disused mines & tips]bobolewis
This generic risk assessment summarizes hazards engineers may face during inspections of disused mines and tips. Key hazards include: live traffic, driving accidents, drowning in watercourses, confined spaces, contaminated materials, falling, sharp objects, poor lighting, animal attacks, medical emergencies, and collisions with off-road vehicles. Existing controls include high visibility clothing, safe parking, inspections from river banks, prohibiting entry into confined spaces or water over 150mm deep, first aid training, and assessing locations for hazards. Further actions include identifying slip/trip hazards, finding areas with mobile phone reception, and checking lone workers' medical conditions.
1. The Patient Movement Item (PMI) program provides additional medical equipment solely for sustaining patients during transport between medical facilities.
2. PMI equipment is exchanged one-for-one during evacuations so that patients can remain on life support during transport, while also replenishing treatment teams' supplies.
3. Proper management of PMI inventories, maintenance, and replacements is necessary to ensure medical equipment is available for sustaining casualties during transport.
Innovating in simulation architectures for Naval Warfare Training & SimulationJose Carlos Diaz
HLA, since its inception, has been a great success for interoperating simulators although its adoption in real time simulations has been more limited.
The OMG DDS (Data Distribution Service) standard has been specifically designed to be applied in large critical distributed systems and federations of systems-of-systems. Some of the most prestigious organizations around the word have recommended or even mandated its use. NADS has adopted DDS for the foundations of SIMWARE: a disruptive high-performance Simulation middleware. In this paper it is presented one of the use cases where SIMWARE adds great value; in Naval Training & Simulation.
Nowadays almost all of the most advanced Navies of the world are concerned about how to reduce costs of training their crews. Most of surface forces train both at sea and on shore, but seem to prefer at sea training in practice.
A number of exercises could be conducted in port using LVC simulation, possibly at lower cost. But today, there are few training exercises with equivalencies in simulators. Even these equivalencies are only for a small part of all typical mission areas. An important stopper is the complexity of the simulation interoperability technology.
The document discusses disaster management in high-rise residential buildings. It explains that fires require fuel, heat, and oxygen to ignite and discusses strategies to control or isolate these elements to prevent combustion. The primary goal of fire safety is to protect occupants and prevent loss of life and property damage. Indian law mandates minimum fire safety equipment for developed properties as defined in the national building code, which standardizes design and construction requirements.

“Hi! Who’s the one To facilitate occupant-controlled elevator evacuation,
person you’d most like the requirement is to have real time information on the

following:
a. Location and severity of fire – can be obtained from
addressable fire alarm systems
b. Elevator operational status – can be obtained from
monitoring system/supervisory panel (Figure 3)

3. c. Elevator lobby and machine room condition – can be
obtained through closed-circuit television cameras
d. Power supply status – can be obtained from building-
management system (BMS) panel
With all of this information, the building management
team and the emergency responders on each floor can
decide the evacuation strategy (total evacuation or pro-
gressive evacuation or fractional evacuation).
Evacuation Elevator Control Switch
In order to gain exclusive control of the elevator for
occupant-controlled evacuation, NFPA5000 -Annex E recom-
mends manually activating the phase-1 recall. (Using
phase-2 operation for occupant-controlled evacuation is to
be understood, though not detailed, within Annex E.) Fur-
ther guidance on occupant-controlled evacuation elevators
can be taken from HTM05-03 Part-E “Escape lifts in health-
care premises.” This code recommends an “evacuation
control switch” located at the evacuation control point
(i.e., the main exit floor) (Figures 4 and 5a).
Evacuation Elevator Voice Communication System
At this point, human behavior during an emergency
evacuation should be considered. Unless reliable infor-
mation is provided to occupants by authoritative persons,
there will most likely be misconception, panic and
rumors. The occupants will be uncertain of their status;
whether to wait for an elevator, whether the elevators are
in good working condition, etc. NFPA72 recommends a
suitable means of communication (a public addressing
system) for each floor as a part of the fire alarm system.
This includes communication with elevator lobbies. It may
Figure 3: Elevator monitoring system/supervisory panel be noted that this is only a one-way communication from
the command center to selected floors and/or lobbies.
An occupant cannot initiate a call to the command center.

indicators convey the following information to occupants
and evacuation staff:
N The elevator is available for evacuation use (at each
landing)
N The elevator is not available for evacuation use (at each
landing)
N The elevator landings at which occupants wait for
evacuation (at main exit floor)
NFPA5000-Annex E recommends color-coded lights
along with the above illuminated displays to confirm the
status of the elevator at each elevator landing as follows:
Message Displayed Color Code
N “Elevators available for occupant evacuation” – Green light
N “Elevators out of service, use exit stairs” – Red light
N “Elevators are operating normally” – No light
Conclusion
Information on-hand is crucial in evacuation scenarios
to decide for and to execute evacuations successfully.
Through many years of technological development and
analytical thinking focused on the “elevator assisted
evacuation” subject, we now have available workable
concepts, technology and equipment to collate real time
information and to share it for the benefit of users.
Though there is no mandatory requirement by the codes,
so far, it is not an idle subject. All the code organizations
are busy developing a regulation on this subject, which
should soon become a mandatory requirement.
Architects and planners should start using such novel
concepts more on their new projects voluntarily. “Eleva-
tor assisted egress” could help as a standby feature to the
primary egress concept should any of the primary egress
components become redundant. When incorporated,
these features bring a great level of satisfaction to the
designer of having increased the safety features of his
project multifold. The authorities would appreciate the
main egress and alternate egress features, which should
speed the approval process. Only when put into practical
usage, further clarity and refinement on this concept and
equipment can be achieved.
