THREE STEPS USED TO MANAGE HEALTH AND SAFETY AT WORK

A
  1. Spot the Hazard (Hazard Identification)
  2. Assess the Risk (Risk Assessment)
  3. Make the Changes (Risk Control)

Safety Hazard

A
  • source of danger
  • is anything that could hurt you or someone else
  • is any source of potential damage, harm or adverse health effects on something or someone under certain conditions at work

Q

Risk Assessment

A

Assessing the risk means working out how likely it is that a hazard will harm someone and how serious the harm could be

Q

Risk Assessment

A

Whenever you spot a hazard, assess the risk by asking yourself two questions.

  1. How likely is it that the hazard could harm me or someone else?
  2. How badly could I or someone else be harmed?

Q

Risk Control

A

Sometimes you may be able to fix simple hazards yourself.

Example: You can pick up things from the floor and put them away to eliminate a trip hazard

Q

Physical Hazard

A

is an agent, factor, or circumstance that can cause harm with or without contact.

They can be classified as a type of occupational hazard or environmental hazard.

Q

Common Physical Hazard in Tech Support

A

Cables running across the floor. If someone trips, falls and hurts himself because of a cable you ran across the floor.

Risk Control: Use cable ties or cord covers to keep cables organized and out of the way.

Q

Example of Mechanical Hazard

A

Example: If you’re working in a data center or an industrial environment, you might be around servers, cooling systems, or other machinery with moving parts. Accidental contact with these can cause injuries.

Risk Control: For particularly heavy loads, use trolleys, hoists, or other lifting equipment to avoid strain injuries.

22
Q

is the arrangement of different elements (including links,
nodes, and devices) in a computer network, defining how each component interacts and communicates with one another.

A

NETWORK TOPOLOGY

23
Q

a schematic or map of
your existing network that ilustrates the nodes and their
connections.

A

NETWORK DIAGRAM

24
Q

refers to the actual layout and structure of the network, both physical and logical

A

NETWORK TOPOLOGY

Example of Network Diagram

A

Physical layout of a network, logical representation of data flow

34
Q

Layer 1 is the physical layer of the OSI model. For network
design purposes, this means the things you can touch: the
cables and the equipment. But it technically also includes the electrical and optical signaling properties. Layer 1 defines the properties of the cables that are necessary to carry the signals. Layer 1 also worries about wireless signaling used.

A

PHYSICAL NETWORK DIAGRAM

35
Q

Layer 2 is the logical layer of the OSI model. Logical
network diagrams represent network topologies at higher
levels. For example, Layer 3 network diagrams depict routing paths, including static routes, and may indicate BGP peers

A

LOGICAL NETWORK DIAGRAM

36
Q

What are the 7 layers description and layers

A

Layer 1 = Physical = Data
Layer 2 = Data Link = Data
Layer 3 = Network = Data
Layer 4 = Transport = Segments
Layer 5 = Session = Packets
Layer 6 = Presentation = Packets
Layer 7 = Application = Bits
