Slapper Actuated Firing Equipment (S.A.F.E.)

The S.A.F.E. detonating mechanism is an exploding foil initiator with increased resistance to stray voltages of up to 40 volts between the rig and the casing

S.M.A.R.T. is an acronym for

• Specific
• Measurable
• Achievable
• Relevant
• Timely

S – SPECIFIC

A goal should be precisely defined, and mustn’t be vague or ambiguous. Make it as precise as possible:

• Who needs to be involved, in order to achieve this goal?
• How can you encourage this person to collaborate?
• What do you want to achieve? And how will you know that the objective has been achieved?
• When do you want to achieve my goal? What is the exact due date, and why?
• Which capabilities are needed? And which challenges do you need to overcome?
• Why should you achieve the goal?
• Where do you want to achieve your goal? (An answer to this question isn’t always necessary.)

M – MEASURABLE

Goals need to be measurable. Hence, you need to decide about the metrics you want to use for measuring your objectives.

• How can you measure progress?
• And how do you know if you’ve successfully met your goal?

A – ACHIEVABLE

You should be able to achieve your goal within the given time frame. Don’t neglect the encouraging aspect of reaching a goal.

An objective can be ambitious, but keep in mind that not achieving your goal can damage your motivation. Hence, it makes sense to link it with your abilities and competencies.

If you think that you can’t achieve a certain goal, think about your missing skills.

• Are you capable of achieving the goal?
• Do you have the needed skills? If you don’t, how can you acquire them?

R – RELEVANT

A SMART goal should have a direct influence on your overall business goals. If there is no connection between them, consider reviewing the goal again. Chances are that it isn’t relevant enough, so you should aim for something else.

• Why should you achieve this goal?
• What is the impact of achieving the goal?
• How does the goal relate to your overall team and company goals?

T – TIMELY

It’s important to determine a due date for each of your SMART goals. You need to derive suitable tasks, which will help you reach a certain goal. To determine the due date of the overall SMART goal, you need to sum up the estimated time it will take to finish all of the derived tasks.

• What tasks need to be finished to achieve the goal?
• How long does it take to finish these tasks?
• When is the due date for your goal?
• Can the goal be achieved before this date?

Refer Material Safety Data Sheet.

Safety fuse consists of a black powder core covered by plastic yarns and an extruded jacket.

Safety fuse is similar in appearance to detonating cord but has a black core where detonating cord has a white PETN core.

Safety fuse burns at between 90 and 120 seconds per meter and is usually crimed into a plain detonator.

There are a number of significant hazards associated with the use of safety fuse. See attached Safety Bulletin from the WA Regulator

That part of the overall management system which includes organisational, planning activities, responsibilities, practices, procedures, processes and resources for developing, implementing, achieving, reviewing and maintaining the Safety policy, and so managing the risks associated with business of the organisation.

The Scale Distance rule shows the relationship between ground vibration, maximum instantaneous charge and the distance.

The common format is

Where

V = vibration in mm/sec

k = ground transmission constant

D = distance from the blast to the monitor

Q = MIC

a = geological constant

The scale distance rule is used for vibration prediction.

Note that D/Q^0.5 is also known as the scale distance (SD).

A plot of log(PPV) against log(SD) can be used to determine k and a in the scale distance rule.

Generic term referring to variation of delay timing no statistical definition.

The reblasting of oversize rocks resulting from primary blasting.

Secure by lock would normally include one of the following –
• a locked building
• a secure shed with lockable entrances, and if there are windows, that they are locked or barred
• a secure and lockable freight container or explosives magazine
• in the case of ammonium nitrate emulsions a lockable tank.

Quality security locks must be employed. Electronic type locks may be acceptable.

Secure store – a physical secure place where explosives or security sensitive dangerous substances are
kept secure by lock or constant surveillance and where procedures for the following are in place:
• controlling access;
• secure control of keys; and
• documenting of the movement into and out of the secure store of explosives and/or SSDS.
