(C) Requirements for certification and examination.
To become a certified blaster a person must have:
(1) Received a minimum of forty hours of training covering all the topics set forth in paragraph (B) of this rule in a course taught under the supervision of the chief, or in a course, or series of courses, deemed equivalent by the chief. For a person seeking only a limited certification pursuant to paragraph (A)(4) of this rule, the chief may waive some of the required training hours and topics, such that the course or series of courses are relevant to the limited blasting conditions listed under paragraph (A)(4) of this rule;
(2) Worked on a blasting crew for at least two years in mining, excavation, or an equivalent working environment;
(3) Received direction and on-the-job training from a blaster certified or licensed in any state;
(4) Exhibited a pattern of conduct consistent with the acceptance of responsibility for blasting operations; and
(5) Passed a written examination covering, at a minimum, the topics set forth in paragraph (B) of this rule.
(a) A person seeking certification may take the examination after receiving the training required under paragraph (C)(1) of this rule and completing at least one of the two years of blasting crew work experience required under paragraph (C)(2) of this rule. However, upon passing the examination a person shall not be certified until he or she has completed all of the two-year blasting crew work experience requirement.
(b) A person seeking only a limited certification pursuant to paragraph (A)(4) of this rule shall pass a written examination covering only the topics in paragraph (B) of this rule that are relevant to the limited blasting conditions listed under paragraph (A)(4) of this rule.
(D) Certification and recertification.
(1) The chief, or an agency, board or institution authorized by the chief pursuant to paragraph (A)(2) of this rule, shall certify for three years those persons examined and found to be competent and to have the necessary experience to accept responsibility for surface blasting operations in mines. Each person approved for certification shall receive a certificate suitable for office display and a wallet-size identification card. The certificate and identification card shall include, at a minimum, the type of certification, the person's name, certification number and date of expiration, and the name and signature of the chief or of the official of the authorized agency, board or institution granting the certification.
(2) To be recertified without a lapse in certification, a blaster certified under this rule must have:
(a) Applied for recertification no more than ninety days prior to the expiration date of the blaster's current certificate; and
(b) Received a minimum of twenty-four hours of continuing education by attending blasting-related courses, seminars or conferences approved by the chief or an authorized representative, with at least eight hours obtained from an organization or person other than the blaster's employer or its parent company or explosives supplier. A blaster holding only a limited certification pursuant to paragraph (A)(4) of this rule is exempt from meeting the twenty-four-hour continuing education requirement of this paragraph, but must receive a minimum of eight hours of blasting-related training approved by the chief or an authorized representative of the chief.
(3) If a blaster certified under this rule fails to apply for recertification on, or before, the expiration date of his or her certificate, the blaster's certification shall expire, and the blaster shall have thirty days thereafter to apply for recertification without being subject to re-examination under paragraph (C) of this rule.
