Health, Safety and Environmental superintendence should be part of the engineering profession in a country for the purpose of
. o duty of care
o remunerative reasons and
o legal reasons.

HSE superintendence should so consider five broad phases
* Specifications
* Design and prosecution
* Installation and commissioning
* Operation and upkeep
* Changes after commissioning.
* Compliance with the principles requires four essential rudiments
* Identification of safety functions warranted for the safe stoppage
* Assignment of a safety integrity status (SIL) for each safety function
* Use of the safety lifecycle for the engineering design and
* Verification of the SIL achieved for each safety function.

The engineering law of practice takes into consideration the following
* Public safety Giving right-of-way to the safety and well- being of the community and having regard to this principle in assessing arrears to the customers, employers and associates.
* Imminence Direction Taking reasonable path to minimize the imminence of loss of lives, injuries or suffering.
* Factory and construction locality Minimizing implicit menaces involved in the construction and manufacture of engineering products and processes.
* Public/ Community well- being
* Communication
* Conflicts of interest
* Confidentiality

The boon of exercising engineering is entrusted to those capable and who have the responsibility for applying engineering experience, scientific knowledge and creativity for the advancement of earthborn interest and quality of life. Beginning principles of conduct of architects include factuality, honesty and reliability in their service to the society, honourable and ethical practice showing fairness, courtesy and good faith towards customers, associates and others. Architects take societal, artistic, juicy, environmental and safety aspects into consideration and strive for the effectual use of the world’s coffers to meet long term earthborn essentials.

Safety is a concern in fair all engineering design processes. Masterminds should understand safety in the milieu of engineering design and what it means to say that a design is safe against mortal injuries.

Current design styles prioritize moneymaking considerations over environmental bones. In some cases, moneymaking considerations also serve environmental meanings. For prototype, the minimization of stuff used in a structure means fund aresaved.However, either, moneymaking considerations conflict with environmental interests which demand that products be made as durable as possible because of the need to minimize resource operation and waste generation in the long term, If they’re saved at the expenditure of the length of the operating life of a product.

Safety is the negation of menace. So, a design is safe to the extent that it reduces menace. Safe design aims at minimizing menace in the standard sense of this term.

A safe design is the combination of all those procedures and principles that are used by architects to make designed objects safe against accidents leading to mortal death or injuries, long term health movables, damage to the environs or breaking in general.

Several design strategies used to achieve safety in operations of potentially dangerous technology are
* naturally safe design
* safety factors
* negative feedback ( personality- stay) and
* multiple independent safety walls.

Probabilistic Threat Assessment (PRA) is the most common tactics of assessing safety but safe designs are used to reduce threats in the standard (probabilistic) sense but is shy. Safe design strategies are used to reduce estimated percentages of injuries or reducing reservations not only threats. They’re used to manage with hazards and eventualities that can not be assigned meaningful percentages.

There are four (4) main design principles in Engineering practice.

(a) Naturally safe design
This minimizes the ingrained risks in the process as far as possible. Possible hazards are excepted rather than enclosed or goton with. For prototype, dangerous substances are replaced by less dangerous bones and fire attestation accoutrements are used rather than burnable bones.

(b) Safety Factors
Construction should be strong enough to buck burden and disturbances exceeding those that are intended. A common way to draw connate safety reserves is to employ explicitly chosen numerical safety factors areemployed.However, either the earth is calculated to defy twice the maximized cargo to which it’ll be exposed to in practice, If a safety factor of two (2) is employed when constructing a earth.

(c) Negative feedback mechanisms
This is introduced to achieve a clay- check in case of device failure or when the automobilist looses control. Exemplars are safety faucets that let out fume when the pressure is too high in a fume boiler and the dead man’s hole that stops the train when the motorist falls asleep. One of the most important safety measures in the nuclear industriousness is to guaranty that reactors near down automatically in critical situations.

(d) Multiple Independent Safety Hedges
Safety hedges are arranged in chains, so that each hedge is independent of its forerunners (if the first fails, the second is still integral). The first hedges preclude accidents; the same walls limit the consequences of an accident and salvation services as the last resort.

Safety factors and multiple safety walls deal with skepticism as well as troubles. But presently, Probabilistic Trouble Analysis (PRA) is used but doesn’t deal with skepticism. Probabilistic maths can support but won’t substitute the Masterminds’ cleanly responsible judgment ( setting, health and safety culture).

Safety engineering principles also include education of chauffeurs, upkeep of tackle and installations and unusualness reporting are specimens of safety practices of general weightiness.
